The change in pitch heard when a listener or the source of the sound is moving, such as when an ambulance is approaching, is the

• sonic boom

• amplitude

• doppler effect

True or False: Noise pollution can cause damage to the ear, stress, and hearing loss.

• True

• False

Destructive interference occurs when

• waves combine to make a wave of smaller amplitude

• waves bend around or through holes in an obstacle

• waves are absorbed and disappear

An echo is a sound wave that has been

• refracted

• reflected

• diffracted

Sound waves are always

• transverse waves

• longitudinal waves

• electromagnetic waves
