Question

define absolute refractive index and Express it mathematically​

Answer 1

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.

Answer 2

Explanation:

Refractive Index-

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.

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.
