What factors does the refractive index of a medium depend on?


The refractive index of a medium depend on:
Optical density or we can say. nature of a medium .
Smaller the speed of light in a medium relative to air, higher is the refractive index of that medium.
Increase in temperature refractive index of the medium increases.

Final Answer:
