define absolute refractive index and express it mathematically???​

Answer 1

Answer:

HEY✌

Explanation:

Absolute refractive index is the refractive index of a medium in vacuum.

The relative refractive index is generally denoted as n21.

Mathematically deriving it N21= V1 / V2.

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
