Question

4. A wave traveling at 200 m/sec has a wavelength of 2 meters. What is the

frequency of this wave?

Answer 1

Given that,

The speed of a wave, v = 200 m/s

Wavelength,
`\lambda=2\ m`

We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :

`v=f\lambda\\\\f=(v)/(\lambda)\\\\f=(200\ m/s)/(2\ m)\\\\f=100\ Hz`

So, the frequency of this wave is 100 Hz.
