Question

A wave is traveling at a speed of 12m/s and its wavelength is 3 m calculate the wave frequency

Answer 1

f = 4 Hz

Step-by-step explanation:

Given that,

The speed of a wave, v = 12 m/s

The wavelength of a wave,
`\lambda=3\ m`

We need to find the frequency of the wave. We know that the speed of wave is equal to the product of wavelength and frequency. So,

`v=f\lambda\\\\f=(v)/(\lambda)\\\\f=(12)/(3)\\\\f=4\ Hz`

So, the frequency of the wave is equal to 4 Hz.
