Question

What is the frequency of a wave if the velocity is 449.4 m/s and the wavelength is 8.4 meters?

Answer 1

We will have the following:

First, we remember:

`\lambda=(v)/(f)`

Then we will have:

`\left(8.4m\right?)=(\left(449.4m/s\right))/(f)\Rightarrow f=(\left(449.4m/s\right))/(\left(8.4m\right))`
`\Rightarrow f=53.5Hz`

So, the frequency of the wave is 53.5 Hz.
