The circular motion of water molecules extends to a depth that is equal to:
A)wave height/wavelength.
B)wave height/wave period.
C)wavelength/wave height.
D)wavelength/2.
E)wavelength/20.

Question

Quizplus · Accepted Answer

The depth to which the circular motion of water molecules extends is known as the wave base. The depth of the wave base is approximately equal to half of the wavelength (λ/2) of the wave passing over it, so the correct choice is option D.
