Refractive Index is a value calculated from the ratio of the speed of light in a vacuum or air to that in a second medium of greater density.; where n is the refractive index, c is the velocity of light in a vacuum ( 3 × 10 8 m/s), v is the velocity of light in a medium.; The … WebAug 9, 2014 · Meave60. Aug 9, 2014. The equation that relates wavelength, frequency, and speed of light is. c = λ ⋅ ν. c = 3.00 × 108 m/s (the speed of light in a vacuum) λ = wavelength in meters. ν = frequency in Hertz (Hz) or 1 s or s−1. So basically the wavelength times the frequency of an electromagnetic wave equals the speed of light.
