Question

explain absolute refractive index and Express it mathematically?​

Answer 1

Answer:

The refractive index of a medium which is defined with respect to vaccum or air is called absolute refractive index

Absolute Refractive index =ratio of sine of angle of incidence in vaccum or air to the sine of angle of refraction in the medium

Answer 2

Explanation:

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.
