Question

what is refractive index of diamond.??​

Answer 1

The refractive index of diamond is 2.42.

Refractive Index shows the comparison of light speeds in two mediums. Light may travel from rarer to denser medium or from denser to rarer medium. 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.
