Question

explain term absolute refractive index of a medium and write an expression to relate it with the speed of light in vacuum

Answer 1

here is your answer

Answer 2

⏪If medium 1 is vacuum or air, then the refractive index of medium 2 is considered With respect to vacuum. This is called Absolute Refractive Index.

⏪If c is the speed of light in vacuum and v is the speed of light in medium, then refractive index is given by:---> c / v .
