What are vibrations?
A wave is x meters long and has a speed of y m/s. Solve for the frequency.
y/x
A disturbance that transmits energy through matter
What is a mechanical wave?
The number of crests that pass a certain point in a given amount of time. (e.g. 3 crests/second)
What is frequency
Distance from one rarefaction/compression to the next rarefaction/compression
Does sound travel fastest through solids, liquids, or gases?
The frequency of a 1-meter long wave is 3 Hz. Solve for the wave speed.
The substance a wave travels through
What is the medium?
The distance from one crest or trough to the next
What is the wavelength?
Low pressure areas in a longitudinal wave
What is rarefaction
The higher the _______ of the sound wave, the higher the pitch (and vice versa)
What is frequency?
The frequency of a wave is 10 Hz and the wave speed is 2 m/s. Solve for the length of the wave in centimeters.
20 cm
A type of wave that occurs in water
What are surface waves?
The amplitude is the distance between the ______ and the crest/trough
What is midpoint?
The change in pressure between the rarefaction and compression points
What is the amplitude?
The greater the ________ of a sound wave, the greater the volume.
What is amplitude?
The frequency of a 98 meter long wave is 35 Hz. Solve for the wave speed.

Answers will vary - likely answers include sound waves or a slinky
The closer you get to a sound’s source, the higher the pitch of the sound. (what is this phenomenon called?)
What is the Doppler Effect?
The speed of a 135-meter long wave is 2.7 m/s. Solve for the frequency.
