Does this wave have a crest and a trough, or compressions and rarefactions? Point out one of each.
A longitudinal wave has compressions and rarefactions. A compression is where the particles/coils are close together. A rarefaction is where they are spread out.
300
When a light wave travels into a new material, it slows down and bends. This is called _____.
Refraction
300
Because sound travels when matter is pushed back and forth, it requires a _____ to travel.
Medium
300
Wave speed = wavelength * frequency
If a wave has a speed of 12 meters per second and a frequency of 4 Hertz, what is its wavelength?
(Do not count this answer as correct if it does not include units!)
3 meters

Identify what these letters are an abbreviation for, and what they are the unit for: Hz
Hertz, frequency
400
Does this wave have a crest and a trough, or compressions and rarefactions? Point out one of each.
Transverse waves have crests and troughs. The crest is the highest point, and the trough is the lowest point.
400
The color of light depends on its _____.
Frequency
400
When a sound wave reflects off a surface and travels back to you, we call it a(n) _____.
Echo

What type of wave is light?
What type of wave is sound?
Light is a transverse wave. Sound is a longitudinal wave.
500
When all colors of light are present, we see _____. When no light is present, we see _____.
White, black
500
The Doppler Effect is when....?
Sound waves are compressed or stretched out by a moving object, resulting in an observer hearing a different pitch than what is actually being produced.
500
Wave speed = wavelength * frequency
Period = 1 / frequency, and frequency = 1 / period
