What is the speed of electromagnetic waves in a vacuum?
Press to flip
Approximately 3 x 10^8 meters per second.
What are the different ways electromagnetic waves interact with matter?
They can be reflected, absorbed, or transmitted when they encounter matter.
Explain the relationship between wavelength and frequency of electromagnetic waves.
Wavelength and frequency are inversely related: higher frequency = shorter wavelength, lower frequency = longer wavelength.
Why are X-rays and gamma rays potentially damaging to cells?
They are ionizing radiation grouped on the right side of the spectrum.
How do the properties of electromagnetic waves impact fields like communications, medicine, and environmental science?
Understanding these properties is essential for advancements in these fields.
How are gamma rays often produced?
Gamma rays often emit from radioactive decay.
Describe the characteristics of gamma rays.
Gamma rays have the shortest wavelength and highest frequency.
Where are radio waves and microwaves placed on the electromagnetic spectrum?
On the far left side, commonly used in communications.
What are the characteristics of radio waves?
Radio waves have the longest wavelength and lowest frequency.
Explain why all types of EM waves can travel through empty space.
Because they do not require a medium to propagate.
Why is it important to study the electromagnetic spectrum?
To understand the origins and effects of waves when interacting with their environments.
How is infrared radiation generated?
Infrared radiation can be generated from the vibration of molecular bonds.
What is the order of colors in visible light from longest to shortest wavelength?
Red, Orange, Yellow, Green, Blue, Indigo, Violet (ROYGBIV).
Explain how visible light, ultraviolet, and X-rays can be generated.
These waves can be emitted when electrons drop down energy levels.
What is a memorization tip for remembering the electromagnetic spectrum?
Begin with visible light and expand outwards, remembering the color sequence ROYGBIV.
