Question

What is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m?

Answer 1

See below...

Explanation:

We know that for a wave

velocity `=` wavelength `*` frequency

`therefore` frequency `=` velocity`/`wavelength

Frequency `=` `20/0.5`= `40`

Frequency is measured in hertz.

Frequency is then `40` hz
