Answer:
The frequency of an ocean wave is 15 Hz.
Explanation:
We are given with, the speed of an ocean wave is 45 m/s. Its wavelength is 3 m
It is required to find the frequency of an ocean wave.
The speed of a wave is given in terms of frequency and wavelength as :
[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.
