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

See below...

#### Explanation:

We know that for a wave

velocity $=$ wavelength $\cdot$ frequency

$\therefore$ frequency $=$ velocity$/$wavelength

Frequency $=$ $\frac{20}{0.5}$= $40$

Frequency is measured in hertz.

Frequency is then $40$ hz
