Sound Waves

Front

A disturbance that travels through a medium as a longitudinal wave

Back

sound

Front

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

Back

diffract

Front

What travels through solids fastest because the molecules are closer together?

Back

speed of sound

Front

The number of wavelengths that pass a point each second

Back

frequency

Front

Material (matter) through which a wave travels

Back

medium

Front

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

Back

pitch

Front

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

Back

Doppler Effect

Front

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

Back

longitudinal wave

Front

The part of a longitudinal wave where the particles of the medium are close together. Options: rarefaction, compression, crest, trough

Back

compression

Front

A part in a longitudinal wave where the particles are spread apart: compression, rarefaction, crest, trough

Back

rarefaction
