please post the correct answer don't blame☺​

Answer 1

Explanation:

Since the speed of light is maximum in vacuum, the refractive index cannot be less than unity.

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.

Answer 2

Answer:

•refractive index is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. the refractive index variable is mostly symbolized by n.....

• the reflractuve medium cannot be less than unity
