Electromagnetic Wave Calculator

Calculate properties of electromagnetic waves using c = f * lambda

Enter either frequency or wavelength to calculate the other and additional properties.

Electromagnetic Wave Formulas

c = f * lambda (speed of light = frequency * wavelength)

E = h * f (photon energy)

T = 1 / f (period)

c = 299,792,458 m/s
