Question

The distance between two consecutive crests is 2.5 meters. Which characteristic of the wave does this distance represent?

amplitude
frequency
period
wavelength
phase

Answer 1

The Correct Answer is Frequency

Step-by-step explanation:

First, there is a known distance between the two consecutive wave's crests. The distance has a known distance of 2.5 meters, Amplitude is just the volume of the waves, period and wavelength are close but does not match the description of the problem.

P.S.: I took the test with a 100% on the first try.

Answer 2

The correct answer is "wavelength".

In fact, the wavelength of a wave corresponds to the distance between two consecutive same-shape points of the wave: for instance, the distance between two consecutive crests, or the distance between two consecutive throughs.

For the wave in this problem, the distance between two consecutive crests is 2.5 meters, therefore the wavelength of the wave is 2.5 m.
