Question

If the speed of the wave is 40 m/s and the wavelength is 10meters, what Is the wave frequency?

Answer 1

`4\ \Hz`

Explanation:

In general, the speed `v` of any wave having frequency `f` & wavelength `\lambda` is given as

`v=f\lambda`

As per given data, we have `v=40\ \text{m/s}` & `\lambda=10\ m` hence

`40=f(10)`

`f=40/10`

`f=4\ \Hz`
