Waves Review

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

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

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

• rarefaction
• compression
• crest
• trough

A part in a longitudinal wave where the particles are spread apart

• compression
• rarefaction
• crest
• trough

A reflected sound wave

• frequency
• pitch
• echo
• rarefaction

Highest point of a wave

• crest
• trough
• wavelength
• frequency

What is the amplitude of this model wave?

• 0mm

• 5cm

• 15cm

• 10mm

Why is a light wave not considered a mechanical wave?

• A light wave is visible to humans.

• A light wave moves faster than most waves.

• A light wave does not have a wavelength.

• A light wave travels through the vacuum of space.

A light wave is considered to be an electromagnetic wave. But what other kind of wave is it?

• Surface wave

• Longitudinal wave

• Transverse wave
