How high or low a sound is; depends on the frequency (greater frequency= higher pitch)

• pitch

• frequency

• sound

• medium

The number of wavelengths that pass a point each second

• crest

• amplitude

• frequency

• pitch

If you want to change the pitch of a sound, you have to change the ___

• frequency

• amplitude

• speed

• volume

This is the unit used to measure the volume of a sound. 

• Decibel

• Medium

• Vibration

• Oscilloscope

This is what you get when sound waves are reflected, or bounce back, off of a hard surface.

• Amplitude

• Pitch

• Volume

• Echo
