The number of wavelengths that pass a point each second

• frequency
• wavelength
• pitch
• amplitude

Material (matter) through which a wave travels

• medium
• Doppler Effect
• sound
• pitch

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

• pitch
• frequency

A wave in which the vibration is in the same direction as that in which the wave is traveling; sound waves

• longitudinal wave
• ocean wave
• transverse wave
• mechanical wave

The part of a longitudinal wave where the particles of the medium are close together.

• rarefaction
• compression
• crest
• trough

A part in a longitudinal wave where the particles are spread apart

• compression
• rarefaction
• crest
• trough

If distance C on the diagram increased, what would happen to the pitch? 

• The pitch would be louder. 
• The pitch would be softer. 
• The pitch would be higher. 
• The pitch would be lower.
