What is meant by refractive index of a medium
Answered by admin @
Definition of refractive index. : the ratio of the speed of radiation (such as light) in one medium (such as air, glass, or a vacuum) to that in another medium.
Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another.
