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


where v is the wave speed and

f is the frequency taken.

The Formula for wavelength for light wave is given by


Where c is the velocity of light,

f is the frequency of the wave.

The wave speed formula is given by


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.
