A wave that requires a medium to travel

• mechanical wave

• chemical wave

• electromagnetic wave

• pitch

A wave in which the direction of vibration of medium is in the same direction as that in which the wave is traveling

• longitudinal wave

• ocean wave

• transverse wave

• mechanical wave

Highest point of a wave

• crest
• trough
• wavelength
• frequency

The number of wavelengths that pass a point each second

• frequency

• wavelength

• pitch

• amplitude

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

• rarefaction
• compression
• crest
• trough

The unit for measuring frequency is the ---

• joule

• hertz

• gram

• newton

What does pitch depend on?

• amplitude 
• frequency
• intensity 
• volume of sound

The shorter the wavelength the 

• shorter the frequency
• higher the freuqnecy
• frequency stays the same
• less energy
