Waves at the shore will start to break when the:
A) water depth is about twice the wavelength.
B) crest flattens into a rounded form.
C) wave period increases to 15 seconds.
D) water depth is about four-thirds the wave height.

Question

Quizplus · Accepted Answer

Waves at the shore will start breaking when the water depth is about four-thirds the wave height. This is because as waves approach the shore, their height increases while their wavelength decreases, causing the wave to become unstable and eventually break. Factors such as the shape of the crest or the wave period do not directly affect the breaking of waves at the shore.
