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.
The Cryosphere is basically ice, and bears interact with it because polar bears use the ice to help them fish and they dig into the ice to make dens.
