Question

define absolute refractive index​

Answer 1

Definition:

The refractive index of a medium with respect to vacuum is known as absolute refractive index.

It is represented as n.

Additional information:

In terms of speed of light in the medium and in vacuum,

n = c / v,

where

c = speed of light in vacuum ≈ 3 × 10 ^ 8 m/s

v = speed of light in the medium

Answer 2

Here is your answer ⤵⤵⤵

The refractive index of the medium with respect to air is considered to be its absolute refractive index.
