Water waves crash in on the beach at a velocity of 3.5 m s. If the distance between the crest of each wave is 4 m, determine the frequency of the water waves. V = fλ.

A) 0.88 Hz

B) 7.0 Hz

C) 14.0 Hz

We are given with the following value:

Velocity = 3.5 m/s

Distance = 4m

We are asked to solve and determine the frequency of the water waves, the solution is shown below:

Velocity = frequency * Distance

Frequency = Velocity / Distance

Frequency = 3.5 m/s / 4m

Frequency = 0.88 Hz

The answer is letter "A" which is 0.88 Hz.
