Answer:
The refractive index of diamond is 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.

. When we say refractive index of diamond is 2.42, it means light is travelling from rarer to denser medium, and speed of light in air (vacuum) is 2.42 times the speed of light in diamond.
oh sorry I will try not to post irrelevnt questions...XD
