Verified By Collegedunia
Solution and Explanation
The absolute refractive index of a medium is the ratio of the speed of light in vacuum (or air) to the speed of light in that medium. \[ n = \frac{c}{v} \] where, $n$ = absolute refractive index, $c$ = speed of light in vacuum, $v$ = speed of light in the given medium.
