Question

What is the frequency of a wave with a wavelength of `5.3*10^-7`?

Answer 1

`5.66 * 10^14Hz`

Explanation:

Using the wave equation

`v = f*lambda`

We rearrange it to:

`f = v/lambda`

Then we sub in the values to get the answer:

`f = (3.8*10^8)/(5.3*10^-7)`

And:

`f = 5.66 * 10^14Hz`
