Question

If the velocity of the wave is 200 m/s, what is the frequency of the wave?

Answer 1

`f = (200 m/s)/lambda`
Without knowing the wavelength, `lambda`; we can not have a numerical frequency.

Explanation:

The formula that relates wave velocity and frequency is

`v = lambda*f`

Plugging in your data and solving for f,

`f = (200 m/s)/lambda`

Without knowing the wavelength, we can not take this any further.

I hope this helps,
