Question

what is ment by absolute refractive index ? write its unit and dimensional formula

i will give extra marks for answer​

Answer 1

Absolute refractive index of a medium is defined as the ratio of the velocity of light in vacuum to the velocity of light in the medium. If c is the velocity of light in vacuum and v in the medium, then n = c/v. The relative refractive index between a pair of media is the ratio of their absolute refractive indices.

Answer 2

Answer:

Absolute refractive index of a medium is defined as the ratio of the velocity of light in vacuum to the velocity of light in the medium. If c is the velocity of light in vacuum and v in the medium, then n = c/v.
