Question

Define refractive index . calculate the speed of light in medium X whose refractive index is 2

Answer 1

Dear Student, Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another..... .Refractive Index = speed of light (c) / Velocity of light in the medium(v) = c/v. Refractive Index = 2 = c/v. v = velocity of light in the medium = c/2.
