Question

Define absolute refractive index and express it mathematicallydefine absolute refractive index and Express it mathematically ​

Answer 1

if the first medium is vacuum then the refractive index of medium 2 is called absolute refractive index

hope it helps you

Answer 2

Answer:

Relative refractive index can be defined as the ratio between the velocities of light V1 and V2 in a given medium. The relative refractive index is generally denoted as n21. Mathematically deriving it N21= V1 / V2.

Absolute refractive index of a medium is the refractive index with respect to its volume. C/V is the ratio of light’s velocity in vacuum to light’s velocity in a medium.
