Question

Define absolute refractive index and Express it mathematically

Answer 1

Explanation:

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.

Answer 2

Explanation:

Absolute refractive index of a medium is defined as the ratio of the velocity of light in a 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=cv.
