For a mechanical wave, amplitude describes

• the amount of energy that is created by a single wave.

• the total distance a particle moves before a wave dies out.

• how far a particle moves before returning to where it started.

• the total amount of troughs and crests created during a wave cycle.

How would you measure the wavelength of a wave?

• Measure from the trough of a wave to its crest.

• Measure from the crest of a wave to its trough.

• Measure from the crest of a wave to the trough of the next wave cycle.

• Measure from any part of the wave to the corresponding point in the next wave cycle.

What does the wavelength of a longitudinal wave determine?

• the decibel level of the sound

• how close together the compressions are

• the location at which the sound was made

• the number of compressions there are in a wave cycle

The relationship between wavelength and amplitude is a(n)

• dependent relationship.

• exponential relationship.

• independent relationship.

• interchangeable relationship.

Changing the wavelength of a wave has what effect on the wave’s amplitude?

• It causes the amplitude to decrease.

• It causes the amplitude to increase.

• It has no effect on the amplitude.

• It causes the amplitude to change in an unpredictable way.
