Answer:

Frequency, f = 15 Hz      

Explanation:

We have,

Speed of an ocean wave is 45 m/s

Wavelength of a wave is 3 m

It is required to find the frequency of an ocean wave.

Speed of a wave, [tex]v=f\lambda[/tex], f = frequency of ocean wave

[tex]f=\dfrac{v}{\lambda}\\\\f=\dfrac{45}{3}\\\\f=15\ Hz[/tex]

So, the frequency of an ocean wave is 15 Hz.
