What is the definition of wavelength?
The distance from one crest to the next crest of a wave
100
What type of electromagnetic wave has the highest energy?
Gamma Rays
100
What is refraction?
The bending of light rays as they enter a new medium
100

Explain how sound and light travel differently through the vacuum of space. 

Sound does not travel through the vacuum of space while light travels the fastest through it. 

200

What is the difference between high and low frequency?

High frequency has more waves that pass by in a certain time period than low frequency 

200

List a common use of gamma rays.

cancer treatment, nuclear reactors, concrete scans

200

What happens to light as it is reflected?

It bounces off an object in a different direction.

200
What state of matter (solid, liquid, or gas) does light travel the fastest through?
Gas
300
What type of electromagnetic wave has the lowest frequency?
Radio Waves
300
What part of the electromagnetic spectrum can be seen by the human eye?
Visible Light
300

What type of images are created by reflection and refraction?

Reflection - mirror image

Refraction - distorted image

300
In what state of matter (solid, liquid, or gas), does sound travel the fastest?
solid
400
If a wave has low energy, what kind of frequency and wavelength does it have?
Low Frequency, Long Wavelength
400

Compare the wavelength, frequency, and energy level of microwaves to infrared light. 

Microwaves have a longer wavelength, lower frequency, and lower energy than infrared. 

400

Explain how we see a shirt as violet. 

Violet is reflected to our eyes while every other color (ROYGBI) is absorbed in the shirt. 

400
What happens to the speed of light rays as they pass through glass?
The light slows down.
500
If a wave has high frequency, what type of energy and wavelength does it have?
High Energy, Short Wavelength
500
List the waves of the electromagnetic spectrum in order from lowest energy to highest energy.
Radio Waves, Microwaves, Infrared Waves, Visible Light, Ultraviolet Rays, X-Rays, and Gamma Rays
500

Explain what causes white light passing through a prism to create a rainbow. 

The prism slows down and bends light as it enters the prism, creating a rainbow.
