WebRefractive index is a dimensionless quantity that describes the speed of light in a medium with respect to the speed of light in vacuum. Most materials have a refractive index > 1 which means that light travels slower in a medium than it does in vacuum. The higher the refractive index, the slower the light moves in that medium.
