Quiz: Introduction to Waves

Which term describes the number of waves passing a point during a certain period of time?

• crest

• frequency

• range

• wavelength

The figure shows a wave. What is the wavelength of the wave?

• 1.5 m

• 3.0 m

• 5.0 m

• 6.5 m

A local surf report provides the height of the wave from the trough to the crest of the wave. How does this relate to the wave’s amplitude?

• It is less than the wave’s amplitude.

• It is equal to the wave’s amplitude.

• It is about twice the wave’s amplitude.

• It is about half of the wave’s amplitude.

What measurement is usually determined by measuring the crest of one wave to the crest of another wave?

• amplitude

• frequency

• range

• wavelength

The figure shows a wave. What is the amplitude of the wave?

• 2 m

• 4 m

• 6 m

• 8 m

A wave pulse occurs at a certain point in three seconds. Which property of the wave can be measured?

• amplitude

• frequency

• wavelength

• wave speed

The figure shows a wave. What is the height of the crest of the wave?

• 1.5 m

• 3.0 m

• 5.0 m

• 6.5 m

Identify three specific quantities that define a wave.

• Amplitude, Wavelength, Frequency

• Speed, Direction, Amplitude

• Wavelength, Frequency, Speed

• Frequency, Amplitude, Phase

The frequency of a wave can be represented in a model by:

• the number of waves that pass a point in five seconds

• the height of the wave

• the distance between two consecutive crests

• the speed of the wave

The amplitude of a wave is described as:

• the height from the crest to the trough

• the height from the center position to the crest or trough

• the distance between two consecutive crests

• the number of waves passing a point in one second
