How does the refractive index of a medium depend on its temperature?

Solution:

The refractive index of a medium drops as the temperature of the medium rises.

With a rise in temperature, the speed of light in that medium increases. As a result, the refractive index = [light velocity in vacuum / light velocity in medium] falls.
