Frequency refers to the total number of revolutions or wave cycles per second. The Formula for period (T) in terms of frequency is given by
If we consider any wave in terms of velocity and wavelength the Frequency Formula is given by
Where f is the frequency of the wave,
V is the wave velocity or wave speed,
$\lambda$ is the wavelength of the wave.
If light wave is considered then frequency is given by
Where C is velocity of light.
Frequency in terms of angular frequency is given by
Where $\omega$ is the angular frequency.
The formula for frequency of a wave is used to find frequency(f), time period(T), wave speed (V) and wave length ($\lambda$). The Frequency is expressed in Hertz (Hz).
