Question

why does the light ray travel slowly in diamond when compared to the vacuum​

Answer 1

Answer:

The light rays travel slowly in diamond as compared to the vacuum due to variation in the refractive index of diamond and vaccum.

Explanation: Speed of light dependents on the refractive index of the medium. Larger the refractive index of the medium lower will be the speed of the light. In diamond the refractive index is high so the speed of light is lower while refractive index of vaccum is lower so the speed of light is higher.
