Light and Color Properties

Good afternoon everyone, good afternoon to all of you. This is once again Tutor Z from SDO Tarlac Province together with Tutor Marky from SDO Bulacan. Tutor Marky, please come up. Hello everyone, hello. It's an amazing afternoon for all of us. Thank you for Tutor Z. We will have another exciting online tutorial this afternoon. So I think Tutor Z, our topic today is really exciting, right? Yes, that is correct, Tutor Markie. Of course, as time goes by, it gets harder. Okay, so Tutor Markie, while we're starting and setting up, I guess it's up to you here with our new visitors and those who are always tuned in to us. Okay, thank you, Tutor C. Hello and happy viewing kay Norish L. Glied, kay Francine Pangilinan from Santo Lucia National High School, kay Laiga Galang Pagdanganan, also from Santo Lucia High School, kay Francine Panalangin, kay Emanuel C. Tarroza, ang ating Tuti of the Week last week. Okay po, si Patrick J. Valderrama, si Jeneline Piedad from Doña Magdalena Gafud National High School, Grade 8 Jasmine ang kanyang section. And also, happy viewing kay Anze King Garcia Sakdalan, kay Andrew Sembrano from also from Santo Lucia High School, grade 8A ang kanyang section. And, ayun nga, kay Patrick J. Valderrama. Of course, mamaya, siguro mag-overflow ang ating comments, Tutor C. That is correct. Alright. So, Tutor Marky, yes, mamaya madadami pa yan kasi maraming active tayong mga learners. And remember that this is not just for us to be annoyed. These are our viewers because these are the ones who are eager to study, no matter what happens. So, Tutor Marquis, last week, we had a very active participant. Would you like to take this opportunity to acknowledge that tutor and that tuti? Yes, thank you, Tutor Z. And of course, of course, Grade 8. Here it is. Sino kaya ang ating Tuti of the Week na kung saan yung Week 5 na ginawa natin? Ayan, lumabas na ang kanyang picture. And of course, ito ay si Laika G. Pagdangaran, ang ating mahusay Tuti of the Week. Siya po ay from Grade 8C. Ang kanyang school ay from Santa Lucia National High School, from Division of Bulacan, Region 3, Central Luzon. Of course. Ang kanyang teacher, si Teacher Mark Joseph Leongson. Ayan, congratulations din po, sir. Congratulations, Laika G. Pagdanganan. Congratulations, Laika Pagdanganan. And also to your teacher, si Sir Mark Joseph Leongson. And of course, siyempre makakatanggap siya ng ating national certificate from E2Li being the Mahusay Tuti of the Week. Right, Tutor Marky? Yes po, ang nakalagay po sa ating certificate, this certificate is hereby presented to Laika G. Pagdanganan in recognition of outstanding participation and great attitude during the E2Li online tutorial session in Science 8. Presented this 18th day of October 2001, signed by Tutor Z and Tutor Marky. Mamaya, Laika, ibibigay ko sa iyo, isesend ko sa iyo ang iyong certificate right after ng ating session. Thank you. Congratulations, Laika. Yes, Tutor Marquis. And of course, maliban kay Laika being our Mahusay Tuti of the Week, meron din tayong Mahusay School of the Week, Tutor Marquis. Ayan. Of course, ang ating Mahusay School of the Week. Congratulations po sa Ramon National High School. Tutor, you see, from Division of Isabela, Region 2, Cagayan Valley. So, siyempre, from week to week, tigan natin kung mamaintain nila ang pagiging Mahusay School of the Week. Ayan, of course. Ayan ang kanilang certificate. Congratulations po sa inyong lahat. Tandaan na hindi natin ito ginagawa para lang, sabi ko nga kanina, Tutor Marquis, mairaos, diba? No, we are doing this kasi gusto nating mag-aral. In fact, kahit wala na nga tayo sa school, tayo Tutor Marquis, nag-aaral pa rin tayo, diba? Kasi gusto natin talagang fresh na fresh ang ating mga knowledge, kumbaga. Alright, Tutor Marquis, today ito ang ating module. class. I do believe pare-pare sa man tayo ng module. Nagiging learning activity sheets nga lang sa mga divisions or districts na gumagawa ng learning activity sheets. It's about quarter one module five, colors of light tayo. Last week, pinag-aralan natin yung tutor, Marky? Ito is something po sa speed. Ay, speed. Sa sound po. Yung temperature and the speed of light. Yung kanilang relationship. Aha. Of course. That is correct. And today, Okay, Tutor Marky, ano ba ang ating sinusundang gabay sa ating discussion today? Okay, thank you po. So, grade 8, ang ating most essential learning competency for this afternoon is to explain the hierarchy of colors in relation to the energy of visible light. So, it is under the most essential learning skill or yung MELCS na tinatawag natin. That is correct. And also, at the end of this session, Tutor Marky and class, ito yung mga dapat nating makuha. Even if we're not perfect, as long as we achieve our goal. And that is, the first tutor marquee, demonstrate the existence of the color components of visible light using a prism or diffraction grating. Those are the ones we will define later, tutor marquee. How about the other two tutor marquee? Okay, the second objective for this afternoon is to explain the hierarchy of colors in relation to energy. And for our third objective is to explain... that red is the least bent color and violet the most bent color according to their wavelengths and frequencies. Yes, that is correct. And Tutor Markie, I told you on Messenger, our topic today is a lot of blood because in just 45 minutes, we need to finish three lessons. So grade 8 class, we just summarized it with Tutor Markie because we just need to get the... pinaka main gist or main idea ng tatlong lesson na to, we will be good na doon sa ating topic for today. Lesson 1 is Colors of Light. Lesson 2, Hierarchy of Colors or yung parang ranking nila, Tutor Marquis, diba? And paano sila nagbe-bend. Alright. So, Tutor Marquis, let's do a quick recap. Palitan tayo dito. Para naman mag-refresh pa rin yung kanilang mastery, not memory kasi yung memory pag nadapa nakakalimutan eh mastery nung last topic natin so tutor Marky, what is sound? so here from our last week or in our previous lesson sounds are caused by vibrations referring to the back and forth movement of objects ayan, so pag ginawa ka natin sabi ko nga, pag ginawa ka natin yung ating leeg, so pag nagsalita tayo magsalita tayo, meron tayong vibration na now na feel. And then, magkapurosay ng sounds. That is correct, Tutor Markie. And also, Tutor Markie and class, sound is energy din naman. Kasi nga, as long as may gumagalaw at makakaapekto ng ibang bagay sa paligid, it is considered as energy. And sound is in the form of wave, umaalon. So, sound is the effect of vibration of the particles of matter, like air molecules. Sabi ko nga, Tutor Markie, diba? The sound is actually the air molecules that pass the vibration. That's why in space, there's really no sound. Even in a movie with special effects sound, there's really no sound. Because it's vacuum. There are no molecules that pass. Just like this one, Tutor Markie and Class. For example, the object that vibrated was the billiards' head. So its vibration was hit by the first molecule. And that molecule also hit... and the energy is transferred to the next molecule. Isn't that right, Tutor Marky? Yes. So there, we can see the grading. The example that Tutor Z presented. There. Yes, that is correct. This is what we call a class of tuning fork. Actually, I saw that in school. We have that. I didn't know. So when Tutor Marky is selected, it vibrates. So that's a good example of an object. sa Science Lab natin para ipakita yung vibration. And tulad ng sinabi namin ni Tutor Markie kanina lang last week, ang sound actually na naririnig natin is yung vibration na ipinapasa-pasa ng mga air molecules hanggang ito ay tumama sa ating eardrum. Diba, Tutor Markie? Yes po. So yung sound wave na yan, pag pumasok sa ear natin, yun yung time na naririnig natin yung sound. And of course, because of the vibration. Yes, and that vibration is brought by the molecules that pass through. What can you explain here, Tutor Martin? There it is. And for us to be able to see or to hear a certain sound or sound wave, of course, it will be propagated with this particular term. We have the solid, the liquid, and the gas. And from this, the more quickly the... the vibration or the travel of the sound wave from gas up to solid. So it means that the speed of sound in the solid tutor Z is faster compared to the liquid and gas. That is correct. Because in a solid tutor marquee and class, the molecules that will pass will be next to each other. That's why it will reach the other end quickly. Alright? So tutor marquee, you just have to say it if you have something to beat. This is a tutor marquee. You can refresh them here. There. So we have different factors, grade 8, that may affect the speed of sound. So hello to our viewers. So we have here the elasticity. Okay? is the fact that... If we apply force, it will immediately return. Or the example we have here is the rubber band. So the second one is the density of the medium. So it may be determined by amount of mass per area on space or volume of the material. And the third one, this is the highlight of our topic last week, the temperature. As temperature increases or getting hotter, the molecules become more active. The sound can travel faster. So ibig sabihin, the more na mas mainit, The higher the temperature, the faster the sound travels. Yes. Hello to Andrew Zambrano. Yes. Yes, Tutor Marky, that's right. I noticed that they're increasing. So just take time, Tutor Marky. Insert it so we can talk to them. Yes. For them. This is Tutor Marky, the trivia about life that I want to share with you and you too, Tutor Marky. Class. Do you know that the colors we see from objects are reflected color waves from the white light spectrum? We'll explain that later with Tutor Markie. Actually, Tutor Markie, that's why you noticed what we were talking about, class. Our jacket is actually green. Why is it different from the camera? Because, class, the color of the object that we see is not the color of the object itself, but the specific color of the white light that is reflected. It's going to our eyes. And coincidentally, the spectrum didn't pop up correctly in our jacket, Tutor Markie. Alright? So if you'll notice, class, we're seeing different colors because it is actually coming from the white light. And that is the sunlight. Okay? Because our eyes, Tutor Markie, have receptors and nerves that identify, like in a computer, there's a code that recognizes the pop-up signal. Right? So now you know that the color we see is not really the color of that object, but the colored color from the light. Right? There. There. So before we continue, I will just shout out to our viewers. Hello to Patrick J. Valderrama, to Jenalyn Piedad from Doña Magdalena Gafud National High School, to Patrick J. Valderrama from San Tolisio National High School, to Paul Henshaw Clarice, to Jalen Rose de Guzman, Okay, kay Andrew Sembrano, Patrick J. Valderrama, kay Marielle Kyle Lustre-Ramos. Ayan. Actually, tutors, nilalagay nalangin yung pangalan ng teacher nila. Assessor Mark Joseph Leongson, Ryan J. Cornelia Soliva, kay Levis Tolentino Yumang, kay Tricia Abigail D. Son Santos, Maria Victoria Tolentino, Maria Janelle A. Catalig, ayan, Emmanuel Citaroza, who else? Jean Gatchalian. We mentioned the others. Vince Noah Kaling, Laika Galang Pagdangana. Thank you for appreciating her. And Mark William Gregorio. So, of course, Tutor Z, before we forget, to our viewers who are here, let's share and like our online session together. So, I'll give Tutor Z 10 seconds i share natin ang online so punta lang po kayo dun sa pinanonood nyo and then share sa inyong facebook so teresi countdown po tayo ng 10 seconds okay go ahead ready okay 10 9 8 7 6 5 4 3 2 1 ayan so siguro grade 8 dapat na share nyo yung online session natin ngayon ha Okay po. Tutor Isis, kumamaya yung ibang mga nagkakamit ito, babatiin po natin. Yes. And hello kay Emmanuel Terosa, isa sa mga Tuti of the Week natin previously. Yes, very active. Alright, Tutor Marquis, first part, kasi nga tatlo ito, first part is the colors of light. So, nai-share ko na yung isang idea about yung colors, na galing pala ito sa liwanag na nag-iwahiwalay, hindi pala yung actual kulay ng object. So, under this one, and identify not in tutor marquee what is slightly okay so tutor marquee To the owners? Ayan. So, according po dito, light is a form of energy. So, it is also called, grade 8, as radiant energy. So, whether a light or a radiant, same lang po siya. So, it is transported through a travels or travels by electromagnetic or tinatawag nating EM waves. And also, it will radiate to all directions. Mapataas, mapababa, mapa... pagilid or mapatabingi, so it will also radiate. So, yung tinatawag natin yung light. Yes, Tutor Marky. Nagre-radiate siya kasi kapag siyempre open yung light source, so lahat ng direction ay pupuntahan niya. However, diretsyo nga lang yung path. Hindi lang nga siyempre natin nakikita Tutor Marky yung energy mismo eh. Siyempre pag tumapo niyan, diretsyo yan. Katulad doon nakikita niyong gumagalaw diyan screen. Alright? It is made of photons, class. Okay, so super small, that travel very fast because photons don't have mass. You know the mass, right? There's a body and weight involved in it. So because it doesn't have mass, it's super light, tutor Marky. And the approximate speed, tutor Marky, is? 300 million meters per second. So grade A, we'll remember that. 300 meters per second. That is correct. So that's basically where Light Tutor Marky and class are made. Photons, sabi niya dito, are massless bundles of electromagnetic energy that travel only in a straight line. But the photon particles radiate outward from the source. Yung nga yung sinabi namin kanina na ang light nagtatravel lang ng diretsyo, pero kapag open yung source, siyempre lahat ng direksyon ay kanyang pupuntahan. Tutor Marky? Ayan. So we have here light waves travel from their sources in a straight line. Yung gaya nung nabanggit ni Tutor si kanina. It is in different... direction. At yung nagra-reject tayo, yung tinatawag nating race. Yes. That is correct, Tutor Markie. And kitang-kita nyo naman, kaya nga siya tinawag na light waves. Kasi actually, hindi naman ito talaga physical na ganyan, Tutor Markie. Kaya lang yung mga scientist natin, nung may instruments sila nag-reading, yan ang nakita nila na nagwe-wave pala ang light. Kaya tinawag na light waves. At ang tawag dyan, class, ay race. Alright. So like energy, cannot move object, Tutor Marky. Of course, kasi wala nga siyang mass. Wala siyang katawang para tumulak or humila. But it can be converted into another form of energy that can do work. Example, Tutor Marky, are? Okay, the first one is the photosynthesis and the second one is the solar energy. Ayan. Alam na alam na ng mga grade 8 dyan kasi lower grade dyan. Okay, so punta na tayo sa actual. actual source natin tutor marquis ng light okay so pag-uusapan natin para makarelate ang lahat is yung sunlight tutor marquis can you discuss this to them tutor marquis oh yan so of course iba yung tinatawag nating sunlight so ito yung lagi nating napapansin pagising tayo ng maaga ito yung nagpapagising sakin pag sa atin so sunlight is a radiant energy that travels as the visible light so of course yung sunlight ang sources po nya and of course yung sun kaya nga sunlight So it is the only EM that can be seen by our naked eye. Is that right, Tutor Z? This is the only thing we see, that's why we wake up in the morning. It's already morning. It is because of sunlight. And lastly, a natural light is also called as white light. Hello to Abdul. Hello to Abdul Raman Barry. So my teacher is Ma'am Grace Parungaw from 8K. To Angel Jamaica Antonio. There, to Tricia Abigail Dizon Santos, to Ma'am Melinda Espino Mano, to Rona Estrella Ignacio, Tutor Z, I see here that it's all Santa Lucia National High School, right? There, to Francine Panalangin, to Eliza Nicole Sawal, to Zvan Joaquin, to John Micah Rivera. There, Tutor Z. Alright, we'll be back later, Tutor Mark, with your comments for engaging, right? Alright class, dito sa screen na to, ang tatandaan natin ay yung dalawang... term dyan, Tutor Markie, yung visible light na tinatawag ding white light kasi yan yung pag i-breakdown natin mamaya. So always remember yung term white light, class. Alright? So ano nga ba ito? As energy, class, yung white light is actually, Tutor Markie, a combination of many different colors. Kung baga, class, diba, pag nag-mix tayo ng kulay, may mabubuo tayong babong kulay. In this case sa light, Tutor Markie and class, pag kinumbay natin lahat ng kulay, magiging white. Diba? Imbis na magkaroon ng parang pigment na ibang kulay, magiging white po siya, kaya nga tinawag siyang white light, although it's a combination of many different colors. Tulad... What is the meaning of this? Tutor Markie, what is it called? This is ROYGBIV. Actually, Tutor Z, I saw in our comment, someone answered that the meaning of ROYGBIV is gone. What is ROYGBIV, Tutor Markie? So, ROYGBIV, Tutor Z, or Grade 8, this is the acronym of all colors. We are familiar with what we call rainbow. So, the letter R, that means red. Letter O, that means orange. Letter Y, that is yellow. Letter G for the green. Letter B for the blue. Letter I for the indigo. And letter V for the violet. That is correct. Yes, and actually, Klasian, din mismo yung hierarchy natin mamaya. Kasi when you say hierarchy, eto yung arrangement nila. Katulad sabi ni Manmol Sitarosa, inisa-isa niya yung ROYGB, ganun din si Francine Panalangin. Okay, so alam na natin yung ibig sabihin ng ROYGB. class, eto yung sinasabi natin tutor Marky, diba? Ang white light, sabi ko nga, is actually a combination of many different lights na nandoon sa loob. But in order for us, tutor Marky, na makita silang maghiwahiwalay, kailangan natin silang baluktutin. Because tulad ng sound class na tinuro ni tutor Marky, nagtatravel din ang light. Diba, tutor Marky? Yes, po. Yes, okay. So ano ang tawag Tutor Marky. Actually, I saw it in the comment section. What is Tutor Marky for objects? This is not just a specific thing. Any object that can bend like Tutor Marky. Okay. So, what we call it is reflection. Is it right, Tutor C? If there's a bend, that is reflection. Yes. No, Tutor Marky is the object. Okay. So, the object that makes it reflect. or the one that makes it bend through the refract is the frizzing. So it is a transparent optical element that can reflect or bend wind-wide separating its components based on the color's wavelength. And you know what, Tutor Z? I have here, this is grade A. This is the example of frizzing that we can see on our screen. This is the example of frizzing. If the white light comes out here, it will have a rainbow like what we see on the screen. I'll zoom in. That is correct. And like I said, Tutor Marky, aside from the actual prism, this is any transparent object that can be lighted and reflected. Water can be a prism as well, right? Just like a ballpoint pen, a mirror, something like that. Alright? So note this kind of refraction class. Okay? Pag nag-bend ang light kasi, Tutor Markie, it's called refraction. Pero pagdating sa light, may specific kind of refraction siya. At ito ay tinatawag na dispersion. Okay? So once again, bago tayo lilipat sa susunod, ang object, kahit anong transparent na pwede mag-breakdown ng white light, ay tinatawag na prism. Ang pagbaluktot ng light ay refraction. At ang tawag sa refraction ng light ay dispersion. Very good. Remember that because we will return to our activity. Tutor Marquis. Okay. Hello to Renaline Taloso Calamayan. Watching from Alibaba National High School in Mariano to this way from SDO Isabela. And also to Kate Louise Ablaza. And to Lorenzo DRG from Pulong Buhangin National High School. So, I will just add, Tutor C, because we have what we call a prism, you know, Grade 8, the prism that we consider is our atmosphere. So, the atmosphere is the prism, so we can see the different colors here in the world. That's why we have a rainbow, Tutor Marky, right? Yes, sir. Yes. So, Tutor Marky? So the spectrum. So from here, we have here the spectrum. So while these bands of colors are separated by their different degrees of refraction, and that is the spectrum. Yes. You actually, Tutor Marky, the ROYGB that we saw earlier, white light, and when they separate, when they separate, what we call in the separation of colors of white light is spectrum. Okay. So that's another term. Again, spectrum. the separate colors of the white light. Okay. There. We're already on the lesson 2 because we're together. I hope, Tutor Marky, they remembered the terms earlier. What are they? prism, refraction, dispersion, and the last one, spectrum. Very good. That's the title of our topic. Tutor Markie and class, we're here in the hierarchy of light. Or the order, Tutor Markie, their arrangement. The one we call ROYGB. Tutor Markie, please read this. There. Grade 8, let's read it together. The arrangement of the colors of light follows the intensities of the colors, the wavelengths, the frequencies, and the energy. And that is called the hierarchy of light. So based on the meeting tutors, we have three things here. I just noticed, so intensities, wavelengths, frequencies, and energy. There are four. Yes. Okay. So actually, tutor Mark, the intensity of the three. The intensity of the three. Yes. Let's find out what Tutor Markie said about Wavelength, Frequencies, and Energy so that we can understand why they became ROYGB. Okay, class. In this module, here it is. So, we will explain each one of them, Tutor Markie, Wavelength, Frequency, and Photon Energy. We will not show the Photon Energy, Tutor Markie, because it is inside itself. But the Wavelength and Frequency, we will see it in the reading. Okay? So, you will notice that the violet has a wavelength of 380 to 445. The red is 620 to 750. So, before we go to the explanation itself, I will ask Tutor Markie to explain this so that they can understand this easily. The wavelength class, you remember that it moves like this, right? When we say wavelength, it is the distance between two waves. So, it means that the violet Compared to red, it's closer. Is that right? The two halos are closer. While the red, the two halos, the distance is far. That's what a wavelength means when you see the halos. The frequency of Tutor Markie and class is how many times it moves in a unit time. For example, in one second, how many halos did Violet make? and how many waves were made by red. So that's what we're looking for in wavelength and frequency, Tutor Marky. And let's explain to them clearly. Here, Tutor Marky, this is the best arrangement because, Roy, you should be the first one to do red. I don't know why, but the violet was the first one. So this is also the same class, just reversed so that we can follow the hierarchy that red is the first on the list, violet is the last. Frequency applied, Tutor Marky. There. So the frequency in light, it refers to the number of waves passing a certain point in one second. And it measures in hertz and its units of cycle per second. That's the unit of frequency, hertz. Yes. So when we measure the frequency of light, we use hertz. And again, the frequency is how many waves it made in one second. Okay? Emmanuel Citaro mentioned here, the more energy in the wave, the higher its frequency. Very good, Emmanuel. Very active. He's fast in doing that. Compared to the red, the wave is just a little every second. Gilbert Francisco said, violet is more intense. That's correct. At least, he understood it in Tagalog so it can be applied. Tutor Marky, please continue this. There. So in terms of the frequency of light, the visible color has a frequency ranging from 430 trillion hertz and it can be seen as red. However, in terms of the violet, it has 750 trillion hertz. So it means that there are more frequencies of violet compared to red. So any frequencies below or above are not visible to the human eye. and see you next time Ryan J's Violet has the lowest wavelength Red has the highest wavelength Violet has the highest frequency And red has the lowest frequency So now we're on frequency Later we'll talk about wavelength That is correct That's right, Turo Marquis The last bullet you read When the hertz Or violet Passes We won't see it anymore It's just white or black diba kasi nga brinaked down yung kulay alright energy naman po tayo ako nato tutor Marky pag energy naman nakita natin kanina yung table natin Wave frequency is related to wave energy, Tutor Marky. The more energy in the wave, the higher its frequency. That's what you read in their comment, that Violet has more waves, so her energy is higher. Let's imagine the kid on the other side. As soon as he jumps, he has more energy. In one second, he jumps a lot. So that's the analogy. Is that right? While the lower frequency... the less energy in the wave. So, connect the energy and frequency. The more wave, the more frequency, the more energy. Like your comment earlier, Mariel Kyle Lustre Ramos said, the lower the frequency is, the less energy in the wave. Very good. Violet, because it has the most wave or frequency, it has the highest energy. The red, it has a small wave or frequency in a unit. time, tulad ng one second, mas konti yung energy niya. Very good, class. Very good. Nagbasa natin sa comment dito talaga na nagkakaroon din sila ng analyzation in terms of the wavelength, yung energy, at saka yung frequency. Kung baga, ay, ganun pala yun. The more na mas malapit kay ganito, mas malapit kay dyan, nagkakaroon sila ng ito ba increased, or ito ba mababa. Yes, that is correct. I'm good. We're really happy because we're not just the class. Our goal is to learn and interact with you. We can see it in your comments. You're all very good. I hope you're all like that. Tutor Markie, this is the wavelength that we talked about earlier. We talked about frequency, Tutor Markie. That's the number of alons. And who has the most alons in a unit time, like one second. That's the most energy. And the wavelength, can you read it, Tutor Markie? What is the wavelength? So the wavelength, we mentioned earlier, it is the distance between corresponding points on subsequent waves measured from peak to peak, or what we call the crest, the top one, and to throw, or between two corresponding points of waves. The throw and the press here is at the bottom. So it is measured in nanometer or symbolized by small letter N and M. Hello po kay Ma'am Teresa Murillo. Hello po dyan. Kay Fulgencio Clarice, kay Ryan, Jake, Soliva, and Francine Panalangin. And thank you for giving your learnings through the comments. Yes. Sarap-sarap magbasa ng comments nyo guys. Talagang parang ano, diba? Parang nasa Class A tayo na section. You can measure wavelength from peak to peak, throw to throw, or between. That is correct. So, the wavelength is very simple. I'm enjoying it because the topic is very simple. The wavelength is the distance of the wave. Either you measure the peak to peak, or the two at the bottom, or the two at the middle. nila okay yung ah It's called in-between. Alright, so that's the wavelength. The most wavelength in a second, the most frequency, the measurement of the wavelength tutor marquee is smaller. So this class, wavelength of violet, is closer to each other compared to the wavelength of red. Thus, the wavelength of violet has higher frequency and energy. So even you, you already understand that the wavelength is smaller, the wavelength is smaller, the frequency is higher. the higher the energy. So, there. It's easy for us to understand our table and it's easy for us to answer the module using that table, Tutor Markie. Okay. Tutor Markie, please show us this. There. So, here, through the wavelength, so within the spectrum, so violet, we can also read in the comments earlier, violet has the shortest wavelength and red has the longest wavelength. So, it means, to me hand While the color reaches red, so our rainbow is arranged, while it reaches red, the wavelength gets longer. While it reaches violet, it gets smaller or more visible or it gets smaller or our wavelength becomes short. Yes. Tutor Markie, before we continue, I saw a question here. Why is red so attractive to the eyes? Do you have an idea, Tutor Markie? Wavelength. Will you notice, Class, that fast food is going orange to red? Yes. Why is that? It's more attractive. Tutor Markie, kasi ibang ano na to, pasadaan lang natin mabilisan. The colors kasi also affects our emotions. Kaya nga, di ba, kung gusto mong kumalma, green ang tingnan mo. Pero kapag red at saka yung orange, mas ginaganahan ka. Ewan ko ba, basta nakaka-apekto sa ano, di ba? Either gaganahan ka sa emotion mo or kung kumbaga sa fast food, magugutom ka, gusto mong kumain ng kumain, di ba? Kaya wala pa ako nakitang fast food na ibang kulay. Okay. Fast food na kulay green, medyo parang boring pero kumakain ka pa rin. Pero Tutor C, ano mabanggit ko nga, mostly yung sa atin, yung mga learners natin, kung sila ay online learner, o yung madalas silang nakatambay sa, or gumagamit ng laptop, syempre yung screen diba dyan, Tutor C, medyo kapag kailangan mo nang i-rest yung mata mo, atitingin ka lang, according to studies, atitingin ka sa kulay green. That is correct. Kasi kalmado. Kalmado. So basically, Gilbert Francisco is more on psychology. More on explaining how it affects our emotions. Okay. So, this is just a point of fact. It's a summary of the points that we saw, Tutor Marky. The red is longest wavelength. So it means that each of its waves is far from each other. That's why the energy is weak. It's like it's shaking. One, two, three. Violet, because the wavelength is close, it means that the frequency is high, the energy is high. 1, 2, 3, 4, 5. Right? Something like that. Alright. So, let's just remember that for mastery, not memorize. And for the last topic, I'm looking at the time. I hope you get it. We're excited. I'm the tutor, Marky, actually. So hello po kay Tutor Kevin Domingo. Nasabi po niya bright colors din po ang nakikita ng mga babies. Ayan. So may papas. Yes. Hello po kay Tutor Kevin. Shout out po kay Sir Marlon Sanchez. And in addition to that, Tutor Marky, buti na lang sinabi ni Tutor Kevin. Kaya nga class, diba sabi ko, ang kulay na nakikita natin is actually hindi galing sa object, kundi yung tumalbog na kulay. That's why may mga animals na colorblind. kasi hindi nila nakikita yung tumatalbog na kulay actually. Diba? So, yun. Ibang topic naman yun, pero related naman. Okay, bending of colors tayo. Alright, paano ba bumabalok to, Tutor Marquis? Ayan, so it is through the process of refraction, grade 8. So, sabi dito, the bending of light as it passes from one medium to another. Actually, napahapyawan na rin natin to, Tutor Izino, mga nakakaraang topic. So, when light crosses the boundary of... two media or of different optical densities like air, water, frism, so on and so forth. It is a change in light speed occurs between of the change in the optical density. So meaning po dito, so base sa pagkakabasa ko po tutor, see, bawat particular na medium ay magkakaiba sila ng density. So kapag magkaiba ang density, magkakaiba din po ng speed of light. That is correct, tutor Marquis. Tulad ng sound, tutor Marquis. Ano kasi ito, class? When you encounter the word density, ito'y tungkol sa kung gaano karami ang lamang molecules. Kaya nga mas mabilis ang pag-travel ng sounds sa solid, diba? Kasi nga maraming nagpapasahan compared sa air na ang lalayo nung nagpapasahan. Kaya nga sabi niya dito, yung speed of light, tutor Marky and class, naapektuhan din ng density ng tinadaanan nila. Kasi nga, depende dun sa nagpapasahan kung magkakalapit ba or magkakalayo, diba? Katulad nito. Actually, it's here. But before that, because it's here in the black part. Optical density. Optical means what Tutor Marky and Class sees. Density is the content of the object that it's passing through. It's the measurement of a component's ability to slow the transmission of light, resulting to a refraction or bending of the light. Class, let's remember this tutorial. Even if we're speaking in English, what's important here is that we get the Tagalog. idea, right? So that we can really use it. So if light passes through an optical density object, it means it can pass through, depending on the density of that thing, the light will be reflected and the tutor marquee will be reflected because the molecules will bring light energy. Like this, tutor marquee, I said it just now. Do you remember this, tutor marquee, in colloids, the way you pass the light? Yes, yes. I remember that. That is correct. That is the idea of the prism class. The light actually is what the molecules pass through. And because their degree of speed will change, of course, there are those that will pass first and there are those that will slow down. That's why there are those that will bounce. and there's a slow-moving effect. The others are aggressive, so it's annoying. So, like this one, Tutor Markie. I saw this in the module and my student said, Sir, please explain this in your episode because it's annoying. So, I bring it down to Tutor Markie and class. What you see is the index of refraction. Ano lang yan? Yan yung pinaka representation ng computation tutor Marky. Okay? Yung nasa baba ng ano, yung may N2. Pag sinabing index of refraction, eto yung tinatawag na refractive index din refers to the measurement measure of the bending of ray of light when passing from one medium into another. So basically, walang physical representation to, kundi representation lang. Okay? So hindi natin yan na kailangan sa ngayon hanggat wala tayong iko-compute. This incident ray, tutor Markie, this is what we call the incoming light. The incoming light. So, that's where the class will start. For example, you have a flashlight. The light of the flashlight is the incident ray. Then, the angle of coincidence, tutor Markie and class, this is the angle that will be built at the point of incidence between the incident ray and the normal. What is the normal that is being said here, class? The normal line? Yung normal line, class, ito yung normally tatalbog. Diba? Kunari tumamang ganyan, ito yung linya ng talbog niya, angle. Pero dahil light tayo, hindi siya tatalbog. Dahil refraction to eh, tatalbog siya. At dahil doon sa normal line na kung saan dapat tatalbog siya, liliku siya doon sa point na yon. At ang tawag doon ay angle of incidence. Okay? Bine-breakdown natin, class, para maintindihan natin yung paliwanag nito. nitong picture na ito. So, ang refracted ray naman, class, ay yung resulta ng pagbaluktot tutor marquee. Diba, incident ray yung papasok? Nung tumama siya sa angle of incidence, imbis na tumalbog tulad ng normal line, bumaluktot siya, so yung bumaluktot na light naman, ang refracted ray. Okay? So, nagigets na ba? At meron pa yatang isa, angle of refraction. Ito naman yung other computation kung saan yung pagbaluktot ng refracted ray, you will see the angle compared to the normal line. What is the normal line again? When it is reflected, this is what follows. But because it did not reflect, it was reflected and it was reflected. Okay? There. Actually, it's good that I did not see any computation in this module, Tutor Marky. Okay. I just understand what we see as a drawing. Alright, Tutor Marky? So, the refractive indices of different colors of light indicate that it travels at different speeds while passing through a refractive medium, which accounts for different degrees of bending. So, like what I said earlier, because they are in a particular medium, they will change their medium, they will change their speed of light, and also, the degree of bending will change when it hits a particular medium. medium. That is correct. And in addition, Tutor Markie, don't forget the energy and wavelength. Of course, if the energy is stronger, the frequency is more active, its reaction is different compared to a low energy or a low frequency. That's why the red is like a bubble, and the violet is like a bubble because they have different frequency, energy, and wavelength. For example, in terms of speed, for example, Yung isa tumakbo mabilis, nakaliko agad. Yung isa namang mabagal, padapa-papa, ganon. So point of fact ulit, Tutor Markie, dito sa ROYGB, ang blue, indigo, and violet. Actually, narealize ko lang nung ginagawa ko ng PowerPoint, Tutor Markie. Yung kulay indigo pala, ganon. Kasi ginamit ko siya sa violet, mali pala ako. So blue, indigo, and violet, these are the colors with the highest frequencies and energy and are bent the most. Alam naman natin yan, basta papunta sa violet, They are very active, the frequency is high, the wavelength is high, and they are the ones that get the most waves. While the red one, the color that has the lowest frequency and energy is bent the least. Take note, class, because it's in the activity. Violet, the color that is most bent. All right. That's it. That's it. That's why I said, I hope you remember. Tutor Marky, you're in charge here. Practice activity. So we have the practice activity entitled, What's More? So first on activity number 13 on your module, observe the illustration and answer the questions after. Write your answers on a separate sheet of paper. So from now, since you are watching us through the comments, we have here a picture or an illustration from White Light, Papunta ng Freezem. passed through the prism and then it bent. So, now, we have here the red which is the n is equal to 1.512 and we have the violet is 1.530. First question, grade 8. Which color has the highest index of refraction? Or small letter n. Is it red or violet? So, which color has the highest index of refraction? So let me see from our comments, so grade 8. So let's just answer, is it red or violet? So there, so Laika Galang Pagdanganan said, higher violet. Tutor Z, our Tuti of the Week. Of course, Laika Lucas said, Francine Panalangin, Jinga Chalian, it's violet. Jalen Rose de Guzman, Daisy de la Cruz and Stella, there, it's up. So let's reveal the answer, Tutor Z. Alright, the color that has the highest index of refraction or pagbaluktot is violet. Very good, guys. Very good. Alright. Basta refraction, pagbaluktot yun, guys, pag sinabing refraction. Tutor Marky? Alright, so for number two. Okay, which color has the lowest index of refraction? Ayan, lowest index. Is it red or violet? Five, four, three. Two, one. Ayan. Alright. So ano ba to? So meron tayo tutor Mark. Ayan. Ayan. So yun, si Laika Galangpagdanganan. Again, okay. Lowest frequency or lowest index of refraction is red. And of course, yung mga comments na rin natin, majority of them answered red. Let's tutor Z. What is our answer? Alright, red. Congratulations sa mga correct answers. Very good. Congratulations, grade 8. And for the number 3 question, based from the illustration, which color is the most bent? Okay. Let's put a number so that it's easier to identify which question we're answering. Okay. So, 5, 4, 3, 2, 1. So, the correct answer, tutor Martin, is? So, let's see. Violet. There. Violet, of course. And number four. Okay, number four. Let's put numbers. Grade eight. Based on the illustration, which color is the least bent? Okay, least bent. That was easy. That was easy. We only have two to choose from. Grade eight. Number four question. Based on the illustration, which color is the least bent? There. So, Leboy Amores said, red. Patrick J. Valderrama said, Angel May Espino. So, Tutor Z, what is our answer? Yes. Ah, yeah. That's correct, Tutor Marquis. If you're watching the class, it's easy, right? Because it's not about being a scientist. The repetition, Tutor Marquis. So we can master who's the highest, lowest, least bent, and our purpose here. Alright, last part. This is only up to five, Tutor Marquis. Assessment. So let's start now. Grade 8, number 1. Which has the least energy among the colors of the rainbow? Is it letter A, green? B, orange? C, red? D, violet? So number 1. Balik tayo sa number 1 to grade 8. Balik tayo sa number 1. So bagay lang ng number and then your answer. So sabi ni Patrick J. Valderrama, it's letter C. Sabi ni Jing Kachalian, it's letter C. Angela Maris, Gregorio, it's letter C, red. Emmanuel Tarroza, Francine Panalangin, Leboy, or Makiya Amores. So, Tutor Z, let's reveal now the answer. Yes, the correct answer, of course, is letter C, red. That's the purpose, right? We'll repeat it. All right, Tutor Margie. Okay, number two question, grade eight. Violet is the most bent among the seven colors because it has the black. So letter A, highest frequency. Letter B, lowest frequency. Letter C is the longest wavelength. Letter D, shortest wavelength. So what is your answer, grade 8? Number 2 question na tayo. Ayan, sabi ni Lai Cagalang, it's letter D. Ni Jinga Chalian, letter A. Okay, Lai, ayan, Lai Cagalang, letter D. So lagyan natin ng number. So Lebo Amores, letter A. Francine Panalangin, A. Ayan, ayan. So Sofia, letter D. So what is our answer in number 2 question, tutor Z? The correct answer is... Sir, is letter D shortest wavelength? So, you will notice, class, if the wavelength is the shortest or the distance of the wave, it is easier to wrap the prism. Okay? Okay, number three question. So, which of the following can separate white light into seven colors? So, is it letter A, box? Letter B, cell phone? Letter C, paper? Or letter D, prism? So, number three question na tayo. So, ayan. Sino ba yun? Anong ba yung nagseseparate from white light into different colors or yung ROYGB that tinatawag natin? Is it box, cell phone, paper, or frisbee? Alright. So, let's wait for the grade A to answer our third question. So, sabi na ni Patrick J. It's letter D. Leboy, letter D. Stella Lapuz, letter D. Laika Lucas, letter D. Tutor C. Let's reveal now the answer for number three. Alright. The correct answer, class, is letter D. And take note, class, prism is not just about the triangle glass. Anything that can bend the light is considered prism, including what Tutor Marky said, the atmosphere. Okay? Alright, number four, last two questions. Number four question. So what refers to the bending of light as it passes from one medium into another? So is it letter A, frequency? Letter B, reflection. Letter C, refraction. Or letter D is wavelength. Okay, number four na tayo. Grade eight. Number four. Ayan, so tigay natin kung ano yung magiging sagot nila. Bending of light. Okay, sabi ni Francine Pangilian is letter B. Emmanuel Tarroza, letter C. Okay, Anzi Kane, sakdalan, letter C. And Erica Dane San Diego, letter C. And most of them answered letter C. So, Tutor Z, what is our answer? Tutor Martin, it's letter C, refraction. Basta bending, refraction yan. Pag tumalbog, reflection. And the last one, Tutor Martin. All right, for our last question, grade 8. Based on the colors of light, what color comes between red and... Yellow. So, the hierarchy here is what we're talking about. Tutor Z. Okay. What comes between red and yellow? Is it indigo? Letter A. Letter B, green. Letter C, orange. Or letter D, violet. So, we're on number five question. Grade eight. Okay. Leboy said. Letter C. Laika said. Letter C. Okay. Patrick. Jay, Stella, letter C, Lorraine, letter C, Laika, Lucas, letter C, Raquel, letter C, Lindsay, letter C. Tutor C, what is our answer in number five? Yes, of course. Dial Tutor Marky. It's Roy G. Beam. Red and orange before yellow. Of course. Very good. Congratulations, guys. It's about mastery. Not memorization. Whatever happens, it's there. Very good. And Tutor Marky. Finally, we are done. Alright, class. Next topic for next week, it will be handled by Tutor Markie. And our topic for that week is heat and temperature. Right, Tutor Markie? Yes, Tutor C. For our Week 7, Tutor C. We'll be back next Monday. Alright. Tutor Markie is almost done. Okay. So, guys, once again, thank you so much for being active. It's not about answering questions. It's more about training our brain. at Mahilig Tayang Mag-Aral. Once again, Tutor Marky, this is Tutor Z from SDO Turlock Province and together with Tutor Marky from SDO Bulacan. Say goodbye, Tutor Marky.

Good afternoon everyone, good afternoon to all of you. This is once again Tutor Z from SDO Tarlac Province together with Tutor Marky from SDO Bulacan. Tutor Marky, please come up.

Hello everyone, hello. It's an amazing afternoon for all of us. Thank you for Tutor Z. We will have another exciting online tutorial this afternoon.

So I think Tutor Z, our topic today is really exciting, right? Yes, that is correct, Tutor Markie. Of course, as time goes by, it gets harder. Okay, so Tutor Markie, while we're starting and setting up, I guess it's up to you here with our new visitors and those who are always tuned in to us. Okay, thank you, Tutor C. Hello and happy viewing kay Norish L. Glied, kay Francine Pangilinan from Santo Lucia National High School, kay Laiga Galang Pagdanganan, also from Santo Lucia High School, kay Francine Panalangin, kay Emanuel C. Tarroza, ang ating Tuti of the Week last week.

Okay po, si Patrick J. Valderrama, si Jeneline Piedad from Doña Magdalena Gafud National High School, Grade 8 Jasmine ang kanyang section. And also, happy viewing kay Anze King Garcia Sakdalan, kay Andrew Sembrano from also from Santo Lucia High School, grade 8A ang kanyang section. And, ayun nga, kay Patrick J. Valderrama.

Of course, mamaya, siguro mag-overflow ang ating comments, Tutor C. That is correct. Alright. So, Tutor Marky, yes, mamaya madadami pa yan kasi maraming active tayong mga learners. And remember that this is not just for us to be annoyed. These are our viewers because these are the ones who are eager to study, no matter what happens.

So, Tutor Marquis, last week, we had a very active participant. Would you like to take this opportunity to acknowledge that tutor and that tuti? Yes, thank you, Tutor Z. And of course, of course, Grade 8. Here it is.

Sino kaya ang ating Tuti of the Week na kung saan yung Week 5 na ginawa natin? Ayan, lumabas na ang kanyang picture. And of course, ito ay si Laika G. Pagdangaran, ang ating mahusay Tuti of the Week. Siya po ay from Grade 8C.

Ang kanyang school ay from Santa Lucia National High School, from Division of Bulacan, Region 3, Central Luzon. Of course. Ang kanyang teacher, si Teacher Mark Joseph Leongson.

Ayan, congratulations din po, sir. Congratulations, Laika G. Pagdanganan. Congratulations, Laika Pagdanganan. And also to your teacher, si Sir Mark Joseph Leongson. And of course, siyempre makakatanggap siya ng ating national certificate from E2Li being the Mahusay Tuti of the Week.

Right, Tutor Marky? Yes po, ang nakalagay po sa ating certificate, this certificate is hereby presented to Laika G. Pagdanganan in recognition of outstanding participation and great attitude during the E2Li online tutorial session in Science 8. Presented this 18th day of October 2001, signed by Tutor Z and Tutor Marky. Mamaya, Laika, ibibigay ko sa iyo, isesend ko sa iyo ang iyong certificate right after ng ating session.

Thank you. Congratulations, Laika. Yes, Tutor Marquis. And of course, maliban kay Laika being our Mahusay Tuti of the Week, meron din tayong Mahusay School of the Week, Tutor Marquis.

Ayan. Of course, ang ating Mahusay School of the Week. Congratulations po sa Ramon National High School. Tutor, you see, from Division of Isabela, Region 2, Cagayan Valley. So, siyempre, from week to week, tigan natin kung mamaintain nila ang pagiging Mahusay School of the Week.

Ayan, of course. Ayan ang kanilang certificate. Congratulations po sa inyong lahat.

Tandaan na hindi natin ito ginagawa para lang, sabi ko nga kanina, Tutor Marquis, mairaos, diba? No, we are doing this kasi gusto nating mag-aral. In fact, kahit wala na nga tayo sa school, tayo Tutor Marquis, nag-aaral pa rin tayo, diba?

Kasi gusto natin talagang fresh na fresh ang ating mga knowledge, kumbaga. Alright, Tutor Marquis, today ito ang ating module. class. I do believe pare-pare sa man tayo ng module.

Nagiging learning activity sheets nga lang sa mga divisions or districts na gumagawa ng learning activity sheets. It's about quarter one module five, colors of light tayo. Last week, pinag-aralan natin yung tutor, Marky?

Ito is something po sa speed. Ay, speed. Sa sound po.

Yung temperature and the speed of light. Yung kanilang relationship. Aha.

Of course. That is correct. And today, Okay, Tutor Marky, ano ba ang ating sinusundang gabay sa ating discussion today?

Okay, thank you po. So, grade 8, ang ating most essential learning competency for this afternoon is to explain the hierarchy of colors in relation to the energy of visible light. So, it is under the most essential learning skill or yung MELCS na tinatawag natin. That is correct.

And also, at the end of this session, Tutor Marky and class, ito yung mga dapat nating makuha. Even if we're not perfect, as long as we achieve our goal. And that is, the first tutor marquee, demonstrate the existence of the color components of visible light using a prism or diffraction grating. Those are the ones we will define later, tutor marquee.

How about the other two tutor marquee? Okay, the second objective for this afternoon is to explain the hierarchy of colors in relation to energy. And for our third objective is to explain...

that red is the least bent color and violet the most bent color according to their wavelengths and frequencies. Yes, that is correct. And Tutor Markie, I told you on Messenger, our topic today is a lot of blood because in just 45 minutes, we need to finish three lessons. So grade 8 class, we just summarized it with Tutor Markie because we just need to get the...

pinaka main gist or main idea ng tatlong lesson na to, we will be good na doon sa ating topic for today. Lesson 1 is Colors of Light. Lesson 2, Hierarchy of Colors or yung parang ranking nila, Tutor Marquis, diba?

And paano sila nagbe-bend. Alright. So, Tutor Marquis, let's do a quick recap. Palitan tayo dito. Para naman mag-refresh pa rin yung kanilang mastery, not memory kasi yung memory pag nadapa nakakalimutan eh mastery nung last topic natin so tutor Marky, what is sound?

so here from our last week or in our previous lesson sounds are caused by vibrations referring to the back and forth movement of objects ayan, so pag ginawa ka natin sabi ko nga, pag ginawa ka natin yung ating leeg, so pag nagsalita tayo magsalita tayo, meron tayong vibration na now na feel. And then, magkapurosay ng sounds. That is correct, Tutor Markie. And also, Tutor Markie and class, sound is energy din naman.

Kasi nga, as long as may gumagalaw at makakaapekto ng ibang bagay sa paligid, it is considered as energy. And sound is in the form of wave, umaalon. So, sound is the effect of vibration of the particles of matter, like air molecules.

Sabi ko nga, Tutor Markie, diba? The sound is actually the air molecules that pass the vibration. That's why in space, there's really no sound. Even in a movie with special effects sound, there's really no sound. Because it's vacuum.

There are no molecules that pass. Just like this one, Tutor Markie and Class. For example, the object that vibrated was the billiards' head.

So its vibration was hit by the first molecule. And that molecule also hit... and the energy is transferred to the next molecule.

Isn't that right, Tutor Marky? Yes. So there, we can see the grading.

The example that Tutor Z presented. There. Yes, that is correct.

This is what we call a class of tuning fork. Actually, I saw that in school. We have that. I didn't know.

So when Tutor Marky is selected, it vibrates. So that's a good example of an object. sa Science Lab natin para ipakita yung vibration. And tulad ng sinabi namin ni Tutor Markie kanina lang last week, ang sound actually na naririnig natin is yung vibration na ipinapasa-pasa ng mga air molecules hanggang ito ay tumama sa ating eardrum.

Diba, Tutor Markie? Yes po. So yung sound wave na yan, pag pumasok sa ear natin, yun yung time na naririnig natin yung sound.

And of course, because of the vibration. Yes, and that vibration is brought by the molecules that pass through. What can you explain here, Tutor Martin? There it is.

And for us to be able to see or to hear a certain sound or sound wave, of course, it will be propagated with this particular term. We have the solid, the liquid, and the gas. And from this, the more quickly the... the vibration or the travel of the sound wave from gas up to solid. So it means that the speed of sound in the solid tutor Z is faster compared to the liquid and gas.

That is correct. Because in a solid tutor marquee and class, the molecules that will pass will be next to each other. That's why it will reach the other end quickly.

Alright? So tutor marquee, you just have to say it if you have something to beat. This is a tutor marquee.

You can refresh them here. There. So we have different factors, grade 8, that may affect the speed of sound. So hello to our viewers.

So we have here the elasticity. Okay? is the fact that...

If we apply force, it will immediately return. Or the example we have here is the rubber band. So the second one is the density of the medium. So it may be determined by amount of mass per area on space or volume of the material. And the third one, this is the highlight of our topic last week, the temperature.

As temperature increases or getting hotter, the molecules become more active. The sound can travel faster. So ibig sabihin, the more na mas mainit, The higher the temperature, the faster the sound travels. Yes.

Hello to Andrew Zambrano. Yes. Yes, Tutor Marky, that's right.

I noticed that they're increasing. So just take time, Tutor Marky. Insert it so we can talk to them. Yes.

For them. This is Tutor Marky, the trivia about life that I want to share with you and you too, Tutor Marky. Class. Do you know that the colors we see from objects are reflected color waves from the white light spectrum? We'll explain that later with Tutor Markie.

Actually, Tutor Markie, that's why you noticed what we were talking about, class. Our jacket is actually green. Why is it different from the camera? Because, class, the color of the object that we see is not the color of the object itself, but the specific color of the white light that is reflected. It's going to our eyes.

And coincidentally, the spectrum didn't pop up correctly in our jacket, Tutor Markie. Alright? So if you'll notice, class, we're seeing different colors because it is actually coming from the white light. And that is the sunlight.

Okay? Because our eyes, Tutor Markie, have receptors and nerves that identify, like in a computer, there's a code that recognizes the pop-up signal. Right?

So now you know that the color we see is not really the color of that object, but the colored color from the light. Right? There.

There. So before we continue, I will just shout out to our viewers. Hello to Patrick J. Valderrama, to Jenalyn Piedad from Doña Magdalena Gafud National High School, to Patrick J. Valderrama from San Tolisio National High School, to Paul Henshaw Clarice, to Jalen Rose de Guzman, Okay, kay Andrew Sembrano, Patrick J. Valderrama, kay Marielle Kyle Lustre-Ramos.

Ayan. Actually, tutors, nilalagay nalangin yung pangalan ng teacher nila. Assessor Mark Joseph Leongson, Ryan J. Cornelia Soliva, kay Levis Tolentino Yumang, kay Tricia Abigail D. Son Santos, Maria Victoria Tolentino, Maria Janelle A. Catalig, ayan, Emmanuel Citaroza, who else? Jean Gatchalian.

We mentioned the others. Vince Noah Kaling, Laika Galang Pagdangana. Thank you for appreciating her.

And Mark William Gregorio. So, of course, Tutor Z, before we forget, to our viewers who are here, let's share and like our online session together. So, I'll give Tutor Z 10 seconds i share natin ang online so punta lang po kayo dun sa pinanonood nyo and then share sa inyong facebook so teresi countdown po tayo ng 10 seconds okay go ahead ready okay 10 9 8 7 6 5 4 3 2 1 ayan so siguro grade 8 dapat na share nyo yung online session natin ngayon ha Okay po. Tutor Isis, kumamaya yung ibang mga nagkakamit ito, babatiin po natin.

Yes. And hello kay Emmanuel Terosa, isa sa mga Tuti of the Week natin previously. Yes, very active.

Alright, Tutor Marquis, first part, kasi nga tatlo ito, first part is the colors of light. So, nai-share ko na yung isang idea about yung colors, na galing pala ito sa liwanag na nag-iwahiwalay, hindi pala yung actual kulay ng object. So, under this one, and identify not in tutor marquee what is slightly okay so tutor marquee To the owners? Ayan. So, according po dito, light is a form of energy.

So, it is also called, grade 8, as radiant energy. So, whether a light or a radiant, same lang po siya. So, it is transported through a travels or travels by electromagnetic or tinatawag nating EM waves.

And also, it will radiate to all directions. Mapataas, mapababa, mapa... pagilid or mapatabingi, so it will also radiate. So, yung tinatawag natin yung light. Yes, Tutor Marky.

Nagre-radiate siya kasi kapag siyempre open yung light source, so lahat ng direction ay pupuntahan niya. However, diretsyo nga lang yung path. Hindi lang nga siyempre natin nakikita Tutor Marky yung energy mismo eh. Siyempre pag tumapo niyan, diretsyo yan.

Katulad doon nakikita niyong gumagalaw diyan screen. Alright? It is made of photons, class.

Okay, so super small, that travel very fast because photons don't have mass. You know the mass, right? There's a body and weight involved in it. So because it doesn't have mass, it's super light, tutor Marky. And the approximate speed, tutor Marky, is?

300 million meters per second. So grade A, we'll remember that. 300 meters per second.

That is correct. So that's basically where Light Tutor Marky and class are made. Photons, sabi niya dito, are massless bundles of electromagnetic energy that travel only in a straight line.

But the photon particles radiate outward from the source. Yung nga yung sinabi namin kanina na ang light nagtatravel lang ng diretsyo, pero kapag open yung source, siyempre lahat ng direksyon ay kanyang pupuntahan. Tutor Marky?

Ayan. So we have here light waves travel from their sources in a straight line. Yung gaya nung nabanggit ni Tutor si kanina.

It is in different... direction. At yung nagra-reject tayo, yung tinatawag nating race. Yes.

That is correct, Tutor Markie. And kitang-kita nyo naman, kaya nga siya tinawag na light waves. Kasi actually, hindi naman ito talaga physical na ganyan, Tutor Markie. Kaya lang yung mga scientist natin, nung may instruments sila nag-reading, yan ang nakita nila na nagwe-wave pala ang light. Kaya tinawag na light waves.

At ang tawag dyan, class, ay race. Alright. So like energy, cannot move object, Tutor Marky.

Of course, kasi wala nga siyang mass. Wala siyang katawang para tumulak or humila. But it can be converted into another form of energy that can do work. Example, Tutor Marky, are?

Okay, the first one is the photosynthesis and the second one is the solar energy. Ayan. Alam na alam na ng mga grade 8 dyan kasi lower grade dyan.

Okay, so punta na tayo sa actual. actual source natin tutor marquis ng light okay so pag-uusapan natin para makarelate ang lahat is yung sunlight tutor marquis can you discuss this to them tutor marquis oh yan so of course iba yung tinatawag nating sunlight so ito yung lagi nating napapansin pagising tayo ng maaga ito yung nagpapagising sakin pag sa atin so sunlight is a radiant energy that travels as the visible light so of course yung sunlight ang sources po nya and of course yung sun kaya nga sunlight So it is the only EM that can be seen by our naked eye. Is that right, Tutor Z?

This is the only thing we see, that's why we wake up in the morning. It's already morning. It is because of sunlight. And lastly, a natural light is also called as white light.

Hello to Abdul. Hello to Abdul Raman Barry. So my teacher is Ma'am Grace Parungaw from 8K.

To Angel Jamaica Antonio. There, to Tricia Abigail Dizon Santos, to Ma'am Melinda Espino Mano, to Rona Estrella Ignacio, Tutor Z, I see here that it's all Santa Lucia National High School, right? There, to Francine Panalangin, to Eliza Nicole Sawal, to Zvan Joaquin, to John Micah Rivera.

There, Tutor Z. Alright, we'll be back later, Tutor Mark, with your comments for engaging, right? Alright class, dito sa screen na to, ang tatandaan natin ay yung dalawang... term dyan, Tutor Markie, yung visible light na tinatawag ding white light kasi yan yung pag i-breakdown natin mamaya. So always remember yung term white light, class.

Alright? So ano nga ba ito? As energy, class, yung white light is actually, Tutor Markie, a combination of many different colors. Kung baga, class, diba, pag nag-mix tayo ng kulay, may mabubuo tayong babong kulay. In this case sa light, Tutor Markie and class, pag kinumbay natin lahat ng kulay, magiging white.

Diba? Imbis na magkaroon ng parang pigment na ibang kulay, magiging white po siya, kaya nga tinawag siyang white light, although it's a combination of many different colors. Tulad...

What is the meaning of this? Tutor Markie, what is it called? This is ROYGBIV.

Actually, Tutor Z, I saw in our comment, someone answered that the meaning of ROYGBIV is gone. What is ROYGBIV, Tutor Markie? So, ROYGBIV, Tutor Z, or Grade 8, this is the acronym of all colors.

We are familiar with what we call rainbow. So, the letter R, that means red. Letter O, that means orange.

Letter Y, that is yellow. Letter G for the green. Letter B for the blue.

Letter I for the indigo. And letter V for the violet. That is correct. Yes, and actually, Klasian, din mismo yung hierarchy natin mamaya. Kasi when you say hierarchy, eto yung arrangement nila.

Katulad sabi ni Manmol Sitarosa, inisa-isa niya yung ROYGB, ganun din si Francine Panalangin. Okay, so alam na natin yung ibig sabihin ng ROYGB. class, eto yung sinasabi natin tutor Marky, diba?

Ang white light, sabi ko nga, is actually a combination of many different lights na nandoon sa loob. But in order for us, tutor Marky, na makita silang maghiwahiwalay, kailangan natin silang baluktutin. Because tulad ng sound class na tinuro ni tutor Marky, nagtatravel din ang light.

Diba, tutor Marky? Yes, po. Yes, okay.

So ano ang tawag Tutor Marky. Actually, I saw it in the comment section. What is Tutor Marky for objects?

This is not just a specific thing. Any object that can bend like Tutor Marky. Okay.

So, what we call it is reflection. Is it right, Tutor C? If there's a bend, that is reflection.

Yes. No, Tutor Marky is the object. Okay.

So, the object that makes it reflect. or the one that makes it bend through the refract is the frizzing. So it is a transparent optical element that can reflect or bend wind-wide separating its components based on the color's wavelength.

And you know what, Tutor Z? I have here, this is grade A. This is the example of frizzing that we can see on our screen.

This is the example of frizzing. If the white light comes out here, it will have a rainbow like what we see on the screen. I'll zoom in. That is correct.

And like I said, Tutor Marky, aside from the actual prism, this is any transparent object that can be lighted and reflected. Water can be a prism as well, right? Just like a ballpoint pen, a mirror, something like that. Alright? So note this kind of refraction class.

Okay? Pag nag-bend ang light kasi, Tutor Markie, it's called refraction. Pero pagdating sa light, may specific kind of refraction siya.

At ito ay tinatawag na dispersion. Okay? So once again, bago tayo lilipat sa susunod, ang object, kahit anong transparent na pwede mag-breakdown ng white light, ay tinatawag na prism.

Ang pagbaluktot ng light ay refraction. At ang tawag sa refraction ng light ay dispersion. Very good.

Remember that because we will return to our activity. Tutor Marquis. Okay. Hello to Renaline Taloso Calamayan.

Watching from Alibaba National High School in Mariano to this way from SDO Isabela. And also to Kate Louise Ablaza. And to Lorenzo DRG from Pulong Buhangin National High School.

So, I will just add, Tutor C, because we have what we call a prism, you know, Grade 8, the prism that we consider is our atmosphere. So, the atmosphere is the prism, so we can see the different colors here in the world. That's why we have a rainbow, Tutor Marky, right?

Yes, sir. Yes. So, Tutor Marky?

So the spectrum. So from here, we have here the spectrum. So while these bands of colors are separated by their different degrees of refraction, and that is the spectrum. Yes.

You actually, Tutor Marky, the ROYGB that we saw earlier, white light, and when they separate, when they separate, what we call in the separation of colors of white light is spectrum. Okay. So that's another term. Again, spectrum.

the separate colors of the white light. Okay. There. We're already on the lesson 2 because we're together.

I hope, Tutor Marky, they remembered the terms earlier. What are they? prism, refraction, dispersion, and the last one, spectrum.

Very good. That's the title of our topic. Tutor Markie and class, we're here in the hierarchy of light.

Or the order, Tutor Markie, their arrangement. The one we call ROYGB. Tutor Markie, please read this.

There. Grade 8, let's read it together. The arrangement of the colors of light follows the intensities of the colors, the wavelengths, the frequencies, and the energy.

And that is called the hierarchy of light. So based on the meeting tutors, we have three things here. I just noticed, so intensities, wavelengths, frequencies, and energy. There are four.

Yes. Okay. So actually, tutor Mark, the intensity of the three. The intensity of the three. Yes.

Let's find out what Tutor Markie said about Wavelength, Frequencies, and Energy so that we can understand why they became ROYGB. Okay, class. In this module, here it is.

So, we will explain each one of them, Tutor Markie, Wavelength, Frequency, and Photon Energy. We will not show the Photon Energy, Tutor Markie, because it is inside itself. But the Wavelength and Frequency, we will see it in the reading. Okay?

So, you will notice that the violet has a wavelength of 380 to 445. The red is 620 to 750. So, before we go to the explanation itself, I will ask Tutor Markie to explain this so that they can understand this easily. The wavelength class, you remember that it moves like this, right? When we say wavelength, it is the distance between two waves. So, it means that the violet Compared to red, it's closer. Is that right?

The two halos are closer. While the red, the two halos, the distance is far. That's what a wavelength means when you see the halos. The frequency of Tutor Markie and class is how many times it moves in a unit time. For example, in one second, how many halos did Violet make?

and how many waves were made by red. So that's what we're looking for in wavelength and frequency, Tutor Marky. And let's explain to them clearly.

Here, Tutor Marky, this is the best arrangement because, Roy, you should be the first one to do red. I don't know why, but the violet was the first one. So this is also the same class, just reversed so that we can follow the hierarchy that red is the first on the list, violet is the last.

Frequency applied, Tutor Marky. There. So the frequency in light, it refers to the number of waves passing a certain point in one second.

And it measures in hertz and its units of cycle per second. That's the unit of frequency, hertz. Yes.

So when we measure the frequency of light, we use hertz. And again, the frequency is how many waves it made in one second. Okay? Emmanuel Citaro mentioned here, the more energy in the wave, the higher its frequency.

Very good, Emmanuel. Very active. He's fast in doing that. Compared to the red, the wave is just a little every second.

Gilbert Francisco said, violet is more intense. That's correct. At least, he understood it in Tagalog so it can be applied.

Tutor Marky, please continue this. There. So in terms of the frequency of light, the visible color has a frequency ranging from 430 trillion hertz and it can be seen as red. However, in terms of the violet, it has 750 trillion hertz. So it means that there are more frequencies of violet compared to red.

So any frequencies below or above are not visible to the human eye. and see you next time Ryan J's Violet has the lowest wavelength Red has the highest wavelength Violet has the highest frequency And red has the lowest frequency So now we're on frequency Later we'll talk about wavelength That is correct That's right, Turo Marquis The last bullet you read When the hertz Or violet Passes We won't see it anymore It's just white or black diba kasi nga brinaked down yung kulay alright energy naman po tayo ako nato tutor Marky pag energy naman nakita natin kanina yung table natin Wave frequency is related to wave energy, Tutor Marky. The more energy in the wave, the higher its frequency.

That's what you read in their comment, that Violet has more waves, so her energy is higher. Let's imagine the kid on the other side. As soon as he jumps, he has more energy.

In one second, he jumps a lot. So that's the analogy. Is that right? While the lower frequency...

the less energy in the wave. So, connect the energy and frequency. The more wave, the more frequency, the more energy.

Like your comment earlier, Mariel Kyle Lustre Ramos said, the lower the frequency is, the less energy in the wave. Very good. Violet, because it has the most wave or frequency, it has the highest energy.

The red, it has a small wave or frequency in a unit. time, tulad ng one second, mas konti yung energy niya. Very good, class.

Very good. Nagbasa natin sa comment dito talaga na nagkakaroon din sila ng analyzation in terms of the wavelength, yung energy, at saka yung frequency. Kung baga, ay, ganun pala yun. The more na mas malapit kay ganito, mas malapit kay dyan, nagkakaroon sila ng ito ba increased, or ito ba mababa. Yes, that is correct.

I'm good. We're really happy because we're not just the class. Our goal is to learn and interact with you. We can see it in your comments.

You're all very good. I hope you're all like that. Tutor Markie, this is the wavelength that we talked about earlier.

We talked about frequency, Tutor Markie. That's the number of alons. And who has the most alons in a unit time, like one second.

That's the most energy. And the wavelength, can you read it, Tutor Markie? What is the wavelength?

So the wavelength, we mentioned earlier, it is the distance between corresponding points on subsequent waves measured from peak to peak, or what we call the crest, the top one, and to throw, or between two corresponding points of waves. The throw and the press here is at the bottom. So it is measured in nanometer or symbolized by small letter N and M. Hello po kay Ma'am Teresa Murillo.

Hello po dyan. Kay Fulgencio Clarice, kay Ryan, Jake, Soliva, and Francine Panalangin. And thank you for giving your learnings through the comments.

Yes. Sarap-sarap magbasa ng comments nyo guys. Talagang parang ano, diba?

Parang nasa Class A tayo na section. You can measure wavelength from peak to peak, throw to throw, or between. That is correct.

So, the wavelength is very simple. I'm enjoying it because the topic is very simple. The wavelength is the distance of the wave. Either you measure the peak to peak, or the two at the bottom, or the two at the middle.

nila okay yung ah It's called in-between. Alright, so that's the wavelength. The most wavelength in a second, the most frequency, the measurement of the wavelength tutor marquee is smaller. So this class, wavelength of violet, is closer to each other compared to the wavelength of red.

Thus, the wavelength of violet has higher frequency and energy. So even you, you already understand that the wavelength is smaller, the wavelength is smaller, the frequency is higher. the higher the energy.

So, there. It's easy for us to understand our table and it's easy for us to answer the module using that table, Tutor Markie. Okay. Tutor Markie, please show us this. There.

So, here, through the wavelength, so within the spectrum, so violet, we can also read in the comments earlier, violet has the shortest wavelength and red has the longest wavelength. So, it means, to me hand While the color reaches red, so our rainbow is arranged, while it reaches red, the wavelength gets longer. While it reaches violet, it gets smaller or more visible or it gets smaller or our wavelength becomes short.

Yes. Tutor Markie, before we continue, I saw a question here. Why is red so attractive to the eyes?

Do you have an idea, Tutor Markie? Wavelength. Will you notice, Class, that fast food is going orange to red? Yes. Why is that?

It's more attractive. Tutor Markie, kasi ibang ano na to, pasadaan lang natin mabilisan. The colors kasi also affects our emotions. Kaya nga, di ba, kung gusto mong kumalma, green ang tingnan mo. Pero kapag red at saka yung orange, mas ginaganahan ka.

Ewan ko ba, basta nakaka-apekto sa ano, di ba? Either gaganahan ka sa emotion mo or kung kumbaga sa fast food, magugutom ka, gusto mong kumain ng kumain, di ba? Kaya wala pa ako nakitang fast food na ibang kulay. Okay.

Fast food na kulay green, medyo parang boring pero kumakain ka pa rin. Pero Tutor C, ano mabanggit ko nga, mostly yung sa atin, yung mga learners natin, kung sila ay online learner, o yung madalas silang nakatambay sa, or gumagamit ng laptop, syempre yung screen diba dyan, Tutor C, medyo kapag kailangan mo nang i-rest yung mata mo, atitingin ka lang, according to studies, atitingin ka sa kulay green. That is correct.

Kasi kalmado. Kalmado. So basically, Gilbert Francisco is more on psychology. More on explaining how it affects our emotions.

Okay. So, this is just a point of fact. It's a summary of the points that we saw, Tutor Marky.

The red is longest wavelength. So it means that each of its waves is far from each other. That's why the energy is weak. It's like it's shaking.

One, two, three. Violet, because the wavelength is close, it means that the frequency is high, the energy is high. 1, 2, 3, 4, 5. Right? Something like that.

Alright. So, let's just remember that for mastery, not memorize. And for the last topic, I'm looking at the time. I hope you get it.

We're excited. I'm the tutor, Marky, actually. So hello po kay Tutor Kevin Domingo. Nasabi po niya bright colors din po ang nakikita ng mga babies.

Ayan. So may papas. Yes. Hello po kay Tutor Kevin.

Shout out po kay Sir Marlon Sanchez. And in addition to that, Tutor Marky, buti na lang sinabi ni Tutor Kevin. Kaya nga class, diba sabi ko, ang kulay na nakikita natin is actually hindi galing sa object, kundi yung tumalbog na kulay. That's why may mga animals na colorblind. kasi hindi nila nakikita yung tumatalbog na kulay actually.

Diba? So, yun. Ibang topic naman yun, pero related naman.

Okay, bending of colors tayo. Alright, paano ba bumabalok to, Tutor Marquis? Ayan, so it is through the process of refraction, grade 8. So, sabi dito, the bending of light as it passes from one medium to another.

Actually, napahapyawan na rin natin to, Tutor Izino, mga nakakaraang topic. So, when light crosses the boundary of... two media or of different optical densities like air, water, frism, so on and so forth.

It is a change in light speed occurs between of the change in the optical density. So meaning po dito, so base sa pagkakabasa ko po tutor, see, bawat particular na medium ay magkakaiba sila ng density. So kapag magkaiba ang density, magkakaiba din po ng speed of light. That is correct, tutor Marquis. Tulad ng sound, tutor Marquis.

Ano kasi ito, class? When you encounter the word density, ito'y tungkol sa kung gaano karami ang lamang molecules. Kaya nga mas mabilis ang pag-travel ng sounds sa solid, diba? Kasi nga maraming nagpapasahan compared sa air na ang lalayo nung nagpapasahan.

Kaya nga sabi niya dito, yung speed of light, tutor Marky and class, naapektuhan din ng density ng tinadaanan nila. Kasi nga, depende dun sa nagpapasahan kung magkakalapit ba or magkakalayo, diba? Katulad nito. Actually, it's here.

But before that, because it's here in the black part. Optical density. Optical means what Tutor Marky and Class sees.

Density is the content of the object that it's passing through. It's the measurement of a component's ability to slow the transmission of light, resulting to a refraction or bending of the light. Class, let's remember this tutorial. Even if we're speaking in English, what's important here is that we get the Tagalog.

idea, right? So that we can really use it. So if light passes through an optical density object, it means it can pass through, depending on the density of that thing, the light will be reflected and the tutor marquee will be reflected because the molecules will bring light energy. Like this, tutor marquee, I said it just now.

Do you remember this, tutor marquee, in colloids, the way you pass the light? Yes, yes. I remember that. That is correct.

That is the idea of the prism class. The light actually is what the molecules pass through. And because their degree of speed will change, of course, there are those that will pass first and there are those that will slow down.

That's why there are those that will bounce. and there's a slow-moving effect. The others are aggressive, so it's annoying. So, like this one, Tutor Markie.

I saw this in the module and my student said, Sir, please explain this in your episode because it's annoying. So, I bring it down to Tutor Markie and class. What you see is the index of refraction. Ano lang yan?

Yan yung pinaka representation ng computation tutor Marky. Okay? Yung nasa baba ng ano, yung may N2. Pag sinabing index of refraction, eto yung tinatawag na refractive index din refers to the measurement measure of the bending of ray of light when passing from one medium into another. So basically, walang physical representation to, kundi representation lang.

Okay? So hindi natin yan na kailangan sa ngayon hanggat wala tayong iko-compute. This incident ray, tutor Markie, this is what we call the incoming light.

The incoming light. So, that's where the class will start. For example, you have a flashlight. The light of the flashlight is the incident ray.

Then, the angle of coincidence, tutor Markie and class, this is the angle that will be built at the point of incidence between the incident ray and the normal. What is the normal that is being said here, class? The normal line? Yung normal line, class, ito yung normally tatalbog. Diba?

Kunari tumamang ganyan, ito yung linya ng talbog niya, angle. Pero dahil light tayo, hindi siya tatalbog. Dahil refraction to eh, tatalbog siya.

At dahil doon sa normal line na kung saan dapat tatalbog siya, liliku siya doon sa point na yon. At ang tawag doon ay angle of incidence. Okay? Bine-breakdown natin, class, para maintindihan natin yung paliwanag nito.

nitong picture na ito. So, ang refracted ray naman, class, ay yung resulta ng pagbaluktot tutor marquee. Diba, incident ray yung papasok? Nung tumama siya sa angle of incidence, imbis na tumalbog tulad ng normal line, bumaluktot siya, so yung bumaluktot na light naman, ang refracted ray. Okay?

So, nagigets na ba? At meron pa yatang isa, angle of refraction. Ito naman yung other computation kung saan yung pagbaluktot ng refracted ray, you will see the angle compared to the normal line.

What is the normal line again? When it is reflected, this is what follows. But because it did not reflect, it was reflected and it was reflected.

Okay? There. Actually, it's good that I did not see any computation in this module, Tutor Marky. Okay. I just understand what we see as a drawing.

Alright, Tutor Marky? So, the refractive indices of different colors of light indicate that it travels at different speeds while passing through a refractive medium, which accounts for different degrees of bending. So, like what I said earlier, because they are in a particular medium, they will change their medium, they will change their speed of light, and also, the degree of bending will change when it hits a particular medium. medium. That is correct.

And in addition, Tutor Markie, don't forget the energy and wavelength. Of course, if the energy is stronger, the frequency is more active, its reaction is different compared to a low energy or a low frequency. That's why the red is like a bubble, and the violet is like a bubble because they have different frequency, energy, and wavelength. For example, in terms of speed, for example, Yung isa tumakbo mabilis, nakaliko agad. Yung isa namang mabagal, padapa-papa, ganon.

So point of fact ulit, Tutor Markie, dito sa ROYGB, ang blue, indigo, and violet. Actually, narealize ko lang nung ginagawa ko ng PowerPoint, Tutor Markie. Yung kulay indigo pala, ganon. Kasi ginamit ko siya sa violet, mali pala ako.

So blue, indigo, and violet, these are the colors with the highest frequencies and energy and are bent the most. Alam naman natin yan, basta papunta sa violet, They are very active, the frequency is high, the wavelength is high, and they are the ones that get the most waves. While the red one, the color that has the lowest frequency and energy is bent the least.

Take note, class, because it's in the activity. Violet, the color that is most bent. All right. That's it. That's it.

That's why I said, I hope you remember. Tutor Marky, you're in charge here. Practice activity. So we have the practice activity entitled, What's More?

So first on activity number 13 on your module, observe the illustration and answer the questions after. Write your answers on a separate sheet of paper. So from now, since you are watching us through the comments, we have here a picture or an illustration from White Light, Papunta ng Freezem.

passed through the prism and then it bent. So, now, we have here the red which is the n is equal to 1.512 and we have the violet is 1.530. First question, grade 8. Which color has the highest index of refraction? Or small letter n.

Is it red or violet? So, which color has the highest index of refraction? So let me see from our comments, so grade 8. So let's just answer, is it red or violet?

So there, so Laika Galang Pagdanganan said, higher violet. Tutor Z, our Tuti of the Week. Of course, Laika Lucas said, Francine Panalangin, Jinga Chalian, it's violet.

Jalen Rose de Guzman, Daisy de la Cruz and Stella, there, it's up. So let's reveal the answer, Tutor Z. Alright, the color that has the highest index of refraction or pagbaluktot is violet. Very good, guys.

Very good. Alright. Basta refraction, pagbaluktot yun, guys, pag sinabing refraction.

Tutor Marky? Alright, so for number two. Okay, which color has the lowest index of refraction? Ayan, lowest index.

Is it red or violet? Five, four, three. Two, one.

Ayan. Alright. So ano ba to? So meron tayo tutor Mark.

Ayan. Ayan. So yun, si Laika Galangpagdanganan. Again, okay. Lowest frequency or lowest index of refraction is red.

And of course, yung mga comments na rin natin, majority of them answered red. Let's tutor Z. What is our answer?

Alright, red. Congratulations sa mga correct answers. Very good. Congratulations, grade 8. And for the number 3 question, based from the illustration, which color is the most bent? Okay.

Let's put a number so that it's easier to identify which question we're answering. Okay. So, 5, 4, 3, 2, 1. So, the correct answer, tutor Martin, is? So, let's see. Violet.

There. Violet, of course. And number four. Okay, number four. Let's put numbers.

Grade eight. Based on the illustration, which color is the least bent? Okay, least bent. That was easy.

That was easy. We only have two to choose from. Grade eight.

Number four question. Based on the illustration, which color is the least bent? There.

So, Leboy Amores said, red. Patrick J. Valderrama said, Angel May Espino. So, Tutor Z, what is our answer? Yes.

Ah, yeah. That's correct, Tutor Marquis. If you're watching the class, it's easy, right? Because it's not about being a scientist. The repetition, Tutor Marquis.

So we can master who's the highest, lowest, least bent, and our purpose here. Alright, last part. This is only up to five, Tutor Marquis. Assessment. So let's start now.

Grade 8, number 1. Which has the least energy among the colors of the rainbow? Is it letter A, green? B, orange?

C, red? D, violet? So number 1. Balik tayo sa number 1 to grade 8. Balik tayo sa number 1. So bagay lang ng number and then your answer. So sabi ni Patrick J. Valderrama, it's letter C.

Sabi ni Jing Kachalian, it's letter C. Angela Maris, Gregorio, it's letter C, red. Emmanuel Tarroza, Francine Panalangin, Leboy, or Makiya Amores.

So, Tutor Z, let's reveal now the answer. Yes, the correct answer, of course, is letter C, red. That's the purpose, right?

We'll repeat it. All right, Tutor Margie. Okay, number two question, grade eight.

Violet is the most bent among the seven colors because it has the black. So letter A, highest frequency. Letter B, lowest frequency.

Letter C is the longest wavelength. Letter D, shortest wavelength. So what is your answer, grade 8?

Number 2 question na tayo. Ayan, sabi ni Lai Cagalang, it's letter D. Ni Jinga Chalian, letter A. Okay, Lai, ayan, Lai Cagalang, letter D. So lagyan natin ng number.

So Lebo Amores, letter A. Francine Panalangin, A. Ayan, ayan. So Sofia, letter D.

So what is our answer in number 2 question, tutor Z? The correct answer is... Sir, is letter D shortest wavelength?

So, you will notice, class, if the wavelength is the shortest or the distance of the wave, it is easier to wrap the prism. Okay? Okay, number three question.

So, which of the following can separate white light into seven colors? So, is it letter A, box? Letter B, cell phone? Letter C, paper? Or letter D, prism?

So, number three question na tayo. So, ayan. Sino ba yun?

Anong ba yung nagseseparate from white light into different colors or yung ROYGB that tinatawag natin? Is it box, cell phone, paper, or frisbee? Alright.

So, let's wait for the grade A to answer our third question. So, sabi na ni Patrick J. It's letter D. Leboy, letter D. Stella Lapuz, letter D.

Laika Lucas, letter D. Tutor C. Let's reveal now the answer for number three. Alright. The correct answer, class, is letter D.

And take note, class, prism is not just about the triangle glass. Anything that can bend the light is considered prism, including what Tutor Marky said, the atmosphere. Okay?

Alright, number four, last two questions. Number four question. So what refers to the bending of light as it passes from one medium into another?

So is it letter A, frequency? Letter B, reflection. Letter C, refraction.

Or letter D is wavelength. Okay, number four na tayo. Grade eight.

Number four. Ayan, so tigay natin kung ano yung magiging sagot nila. Bending of light.

Okay, sabi ni Francine Pangilian is letter B. Emmanuel Tarroza, letter C. Okay, Anzi Kane, sakdalan, letter C.

And Erica Dane San Diego, letter C. And most of them answered letter C. So, Tutor Z, what is our answer?

Tutor Martin, it's letter C, refraction. Basta bending, refraction yan. Pag tumalbog, reflection.

And the last one, Tutor Martin. All right, for our last question, grade 8. Based on the colors of light, what color comes between red and... Yellow.

So, the hierarchy here is what we're talking about. Tutor Z. Okay. What comes between red and yellow? Is it indigo?

Letter A. Letter B, green. Letter C, orange. Or letter D, violet.

So, we're on number five question. Grade eight. Okay.

Leboy said. Letter C. Laika said. Letter C. Okay. Patrick.

Jay, Stella, letter C, Lorraine, letter C, Laika, Lucas, letter C, Raquel, letter C, Lindsay, letter C. Tutor C, what is our answer in number five? Yes, of course. Dial Tutor Marky. It's Roy G. Beam.

Red and orange before yellow. Of course. Very good.

Congratulations, guys. It's about mastery. Not memorization. Whatever happens, it's there.

Very good. And Tutor Marky. Finally, we are done. Alright, class. Next topic for next week, it will be handled by Tutor Markie.

And our topic for that week is heat and temperature. Right, Tutor Markie? Yes, Tutor C. For our Week 7, Tutor C. We'll be back next Monday. Alright. Tutor Markie is almost done.

Okay. So, guys, once again, thank you so much for being active. It's not about answering questions. It's more about training our brain. at Mahilig Tayang Mag-Aral.

Once again, Tutor Marky, this is Tutor Z from SDO Turlock Province and together with Tutor Marky from SDO Bulacan. Say goodbye, Tutor Marky.
