Question

How do you calculate the frequency of a wave?

Answer 1

Frequency

1. The number of the complete waves produced in unit time is called the frequency of the wave.
2. The unit of frequency is Hertz.

Calculation of frequency

Frequency is defined by

$f=\frac{\nu }{\lambda }$ , where $f,\nu and\lambda$ are frequency, velocity, and wavelength of the wave.

$f=\frac{\omega }{2\pi }$, where $\omega$ is the angular frequency of the wave.

If we know the velocity and wavelength of the wave before, then we can easily calculate the frequency of the wave.
