Solution

The correct option is C $n = \frac{c}{v}$
The absolute refractive index is defined as a ratio of the speed of light in vacuum to the speed of light in a given medium.
It is calculated as $n = \frac{c}{v}$ where, c is the speed of light in vacuum and v is the speed of light in the given medium.
