Disturbance that transfers energy from point to point
wave 100
The bottom, or lowest point of a wave
trough 200
Region in a sound wave where particles are pushed together (upward curves)
compression 300
The number of waves produced in a unit of time
frequency 400
Measure of the amount of energy in a sound wave
amplitude 500
The back and forth movement of matter where energy is transferred is called?
vibration 100
TRUE OR FALSE – Does sound travel in a vacuum?
FALSE 200
Sound that does not get absorbed is what?
300 reflected
TRUE OR FALSE – Vibrations move at different speeds in different material and have different wavelengths
TRUE 400
TRUE OR FALSE – When sound waves move through a medium, the molecules travel with the wave to transfer the energy along
FALSE 500
Sound travels fastest through what medium?
solid 100

door 500
With increased frequency would the pitch be high or low?
high 100
TRUE OR FALSE – The higher the amplitude the louder the sound
TRUE 200
The highness or lowness of a sound is called what?
pitch 300
TRUE OR FALSE - The lower the number of waves per unit of time the higher the pitch
FALSE 400
A decrease in amplitude would cause a louder or softer sound?
softer 500
The top, or highest point, of a wave is called what?
crest 100
Animals, such as bats, use what type of communication?
echolocation 200
The distance from the crest of one wave to the crest of another is called what?
