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.
