#### Question

Explain the term absolute refractive index of a medium and write an expression to relate it with the speed of light in vacuum.

#### Solution

The absolute refractive index is the value of refractive index of a medium with respect to the vacuum.

mu_B=c/v

where

c = Speed of light in vacuum

v = Speed of light in medium B

Here, mu_B is the absolute refractive index of medium B.

Is there an error in this question or solution?
