• sound
• wavelength
• pitch
• frequency

Bending of waves around an object (such as through a doorway)

• sound
• diffract
• pitch
• volume

NGSS.MS-PS4-2

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
• sound
• medium

When the sound source moves, the frequency changes
ex. police car siren sounding lower pitch after the car passes

• pitch
• frequency
• Doppler Effect
• medium

The number of wavelengths that pass a point each second

• crest
• amplitude
• frequency
• pitch

A wave that requires a medium through which to travel

• mechanical wave
• chemical wave
• electromagnetic wave
• pitch

• trough
• wavelength

• Solid
• Liquid 
• Gas
• Doesn't Matter
