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
