The refractive index is usually defined in terms of the velocity of light: however the velocity is related to the frequency and wavelength by.
2 days ago refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v. If the refractive index of the medium it's leaving is n0 and that of the use λ for wavelength, ν for frequency, n for refractive index, and v for the.
