Question

The horizontal distance between a crest to the next trough of an ocean wave is 5 meters.

Answer 1

Answer:

10 meters

Explanation:

A wave is a natural phenomenon that travels through a material medium but does not have a permanent effect on the particles of the medium. It can either be electromagnetic or mechanical. The propagation of a wave can be represented by a sinusoidal graph, which has crests and troughs.

A crest is the point of maximum displacement, while trough is a point of minimum displacement. The distance between two crests or troughs gives the wavelength of the wave.

From the question, the horizontal distance between a crest to the next trough is 5 meters which is half of the wavelength.

Thus wavelength = 5 × 2

                             = 10

The wavelength is 10 meters.
