Electromagnetic Spectrum
What are the three types of UV rays?
UV-A, UV-B, and UV-C
A narrow beam of light that travels in a straight line.
Light ray
What type of wave is a light wave?
Electromagnetic wave
What are radio waves often used for?
Communication
A material that does not transmit light.
Opaque
What does light travel the fastest through?
Vacuum
This type of wave makes you feel warm.
Infrared/IR
When light waves come in contact with a surface and bounces off of it.
Reflection
How many types of electromagnetic waves are there?
7
Why are microwaves useful for transmitting information by satellite?
Because they can easily pass through clouds, smoke, and light rain.
When a wave changes direction as it travels from one material to another.
Refraction
If the wavelength of light decreases, what happens to its energy?
It increases.
This type of wave is produced by vibrations in the nucleus of an atom.
Gamma rays
How are the angle of incidence and the angle of refraction related?
They are equal.
How do light waves travel?
In straight lines.
