MATHAMATICALLY , n = c / v

HOPE THIS IS HELPFUL FOR YUH , IF SO PLS SMASH THAT THANKS AND MARK MY ANSWER AS BRAINLIST

Answer 2

Answer:

The amount of change in speed of light in a medium depend upon the property of medium(refractive index) Refractive index is a measure of how much speed of light changes when it enter the medium from air. Absolute refractive index is the ratio of speed of light in vacuum or air to speed of light in the medium
