Calculate Wavelength

You can change the value for the speed of light, because this depends on the medium. The default value is for a vacuum.

wavelength= speed of light / frequency
λ = c / f

wavelength: in nm (nanometers)
speed of light: in m/s
frequency: in 1/s

Please enter two values, the third will be calculated. More comprehensive: Calculator for the Electromagnetic Spectrum.
