Refractive index measurement is actually a measurement of the speed of light in a medium. The speed of light (usually denoted by c) is 299 792 458 m/s in vacuum. In other media the speed of light is lower than this value‚ and the refractive index‚ R.I.‚ of a medium is a measure of how much the speed of light is reduced in the medium. The refractive index (n) of a medium is defined as the ratio of speed of light in vacuum (c) in to that in the medium (v) The speed of light in a medium depends on
