Question

What is refractive index and absolute refractive index

Answer 1

Explanation:

Refractive index means RI of your medium with respect to some other medium. 1μ2 means RI of medium two with respect to medium one. Now absolute refractive index means when your first medium is vacuum or air(if the calculations are not that precise).

Answer 2

${\bold{\red{Refractive\:Index-}}}$

If she is the speed of light in air and v the speed of light in medium,then the refractive index of medium is

μ =

$\frac{speed \: of \: light \: in \: vacuum \: or \: air}{speed \: of \: light \: in \: medium} = \frac{c}{v}$

${\bold{\blue{Absolute\:Refractive\:Index-}}}$

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

The absolute refractive index of a medium is simply called refractive index.
