Question

multiple choice 7.14 points
what does the amplitude of a transverse wave measure?
the distance between two consecutive crests.
the speed of the wave.
the number of crests that pass a point in one second.
the distance between the rest position and the crest of the wave.

Explanation:

• The distance between two consecutive crests is the wavelength.
• The speed of the wave is how fast the wave propagates.
• The number of crests that pass a point in one second is the frequency.
• The amplitude of a transverse wave is the maximum displacement from the rest position. So, it is the distance between the rest position and the crest (or trough) of the wave.

Answer:

The distance between the rest position and the crest of the wave.
