Question

Define the term absolute refractive index of a medium.​

Answer 1

ANSWER. Absolute refractive index of a medium is defined as the ratio of the velocity of light in a vacuum to the velocity of light in the medium. If c is the velocity of light in vacuum and v in the medium, then: n=c/v.

Answer 2

Answer:

The absolute refractive index is the refractive index of a medium in vacuum. More specifically, it is the ratio of the speed of light in vacuum to the speed of light in that medium. It is always greater than one.
