Question

Ocean waves crash on the beach at a

velocity of 4.4 m/s. If the distance
between the crest of each wave is 4m,
find the frequency of the waves.

Answer 1

f = 1.1 Hz

Explanation:

Given that,

The velocity of an ocean wave, v = 4.4 m/s

The distance between the crest of each wave is 4 m.

We need to find the frequency of the waves.

The distance between the crest of a wave is called the wavelength of a wave.

The relation between the frequency, wavelength and the velocity of a wave is given by :

`v=f\lambda\\\\f=(v)/(\lambda)\\\\f=(4.4)/(4)\\\\f=1.1\ Hz`

So, the frequency of the waves is 1.1 Hz.
