WebMathematically, the index of refraction is the ratio of the speed of light through a vacuum and the speed of light through the medium in question. The refractive index can also be calculated by measuring the angle of incidence and the angle of refraction and applying the formula: n = sin (θ i) / sin (θ r) (where n is the index of refraction)
