Waves and Sound Review

What is a repeating disturbance or vibration that transfers energy through a medium or space?

• Energy

• Wave

• Trough

• Wavelength

NGSS.MS-PS4-1

NGSS.MS-PS4-2

These waves do NOT require a medium to transfer energy and include visible light.

• electromagnetic waves

• mechanical waves

• sound waves

• longitudinal wave

NGSS.HS-PS4-1

NGSS.HS-PS4-3

These waves require a medium to transfer energy.

• electromagnetic waves
• light waves
• x-rays
• mechanical

True or false: Sound waves are mechanical waves.

• True
• False

This is the number of waves passing a point in a second

• Frequency
• Amplitude
• wavelength
• crest

NGSS.HS-PS4-1

This occurs when a wave hits an object and bounces off.

• diffraction
• reflection
• refraction
• absorption

Wavelength of a longitudinal wave is measured from this to this.

• rarefaction to compression

• crest to rarefaction

• trough to crest

• compression to compression

A change is frequency of a sound would change this quality of the sound.

• Volume
• pitch
• loudness

The low point of a transverse wave

• crest

• trough

• amplitude

• wavelength

• frequency

Constructive interference will cause waves to:

• Add amplitudes and create a larger wave

• cancel out and decrease in amplitude

• stay the same
