Unit 2 Review: WAVES

How high or low a sound is perceived; depends on the frequency of the wave.

• pitch
• frequency
• sound
• medium

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

• interference
• diffraction
• pitch
• volume

The Doppler effect is the change in ______________ of a wave in relation to an observer who is moving relative to the wave source.

• amplitude

• loudness

• wave speed

• frequency

Tags

NGSS.HS-PS4-1

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

Tags

NGSS.MS-PS4-1

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

• rarefaction
• compression
• crest
• trough

Tags
