Characteristics of waves

Which property of a wave describes how often it occurs?

• speed

• amplitude

• sound

• frequency

What do you call vibrations that move through a medium?

• waves

• crest

• trough

• amplitude

Sound travels through air. What is air an example of?

• medium

• energy

• longitudinal waves

• transverse waves

Select all parts of a longitudinal wave:

• crest

• compression

• trough

• rarefaction

• wavelength

Speed = distance / time. What is the speed of a wave that travels 20 meters in 10 seconds?

• 1 m/s

• 3 m/s

• 2 m/s

• 10 m/s

A wave that vibrates the medium at right angles, or perpendicular, to the direction in which the wave travels:

• transverse wave

• surface wave

• sound wave

• longitudinal wave

How do mechanical waves form?

• When the medium begins to vibrate.

• When the water begins to vibrate.

• When a source of energy causes the medium to vibrate.

• When a disruption causes the medium to vibrate.

Select all parts of a transverse wave:

• compression

• crest

• trough

• rarefaction

• wavelength

The number of waves that pass a given point in a certain amount of time.

How far a wave travels in a given amount of time:
