Dear Student

Asrefractive index= Speed of light in air
speed of light in diamond
This means the ratio of the speed of light in the air and the speed of light in diamond is equal to 2.42.

This means that the speed of light in diamond will reduce by a factor of 2.42 as compared to its speed in air. ... In other words, the speed of light in diamond is 1/2.42 times the speed of light in vacuum.
