Question

A wave with a height of 5 feet and a wavelength of 10 feet has a wave base of?

A. 20ft
B. 10ft
C. 2.5ft
D. 5ft

Answer 1

D. 5ft

Step-by-step explanation:

The wave base of a wave is the depth at which there is no more perturbation of the medium caused by the wave. The wave base of a wave is determined to be half the wavelength of the wave itself.

In this problem, we have a wave with wavelength of 10 ft, so the wave base is

`b=(\lambda)/(2)=(10 ft)/(2)=5 ft`
