Question

Define absolute refractive index of a medium. Find its value for glass in which speed of light is 2*10 raise to power 8.

Answer 1

I think this is ur ans

a number indicating the speed of light in a given medium as either the ratio of the speed of light in a vacuum to that in the given medium (absolute index of refraction) or the ratio of the speed of light in a specified medium to that in the given medium (relative index of refraction). Symbol: n
