Question

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

Answer 1

Answer:

f = 4 Hz

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,

$v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{12}{3}\\\\f=4\ Hz$

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