Refractive index is defined as the relative speed at which light moves through a material with respect to its speed in a vacuum. By convention, the refractive index of a vacuum is defined as having a value of 1.0. The index of refraction, n, of other transparent materials is defined through the equation: n = c/v. where c is the speed of light, and v is the velocity of light in that material.
