Question

The wavelength of a wave is the distance between

a. the crest and the following trough.
b. two consecutive crests.
c. the amplitude and the normal position.
d. the rarefaction and the following compression.

Answer 1

The wavelength of a wave is the distance between

A. the rarefaction and the following compression.

B. the crest and the following trough.

C. the amplitude and the normal position.

D. two consecutive crests.

THE CORRECT ANSWER IS D.

Answer 2

The question asks us to choose the correct answer about the wavelength. The wavelength of a wave is the length of one complete wave cycle. A wave is repeating pattern. It can be measured as a distance from crest to crest or from trough to trough. Answer: The wavelength of a wave is the distance between b. two consecutive crests.
