Deep-Water Waves

Water waves are called deep-water waves when the depth of the water is much greater than the wavelength of the wave. The speed of deep-water waves depends on the wavelength as follows:

Suppose you are on a ship at rest in the ocean, observing the crests of a passing sinusoidal wave. You estimate that the crests are 75 m apart.

Approximately how much time elapses between one crest reaching your ship and the next?

A. 3 s

B. 5 s

C. 7 s

D. 12 s
