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.
