# Wavelength Formula

Here's the definition of wavelength: the difference between two successive crust or trough is called its wavelength. It is denoted by $\lambda$.

Wavelength Formula for any wave given by

$\lambda=\frac{v}{f}$

where v is the wave speed and

f is the frequency taken.

The Formula for wavelength for light wave is given by

$\lambda=\frac{c}{f}$

Where c is the velocity of light,

f is the frequency of the wave.

The wave speed formula is given by

$v=f\lambda$

Wavelength is expressed in m, velocity of wave is expressed in m/s, frequency is expressed in Hz. Wavelength formula is used to find wavelength or frequency if any of these parameters are given.
