Question

define absolute refractive index (for 2 m)​

Answer 1

Answer:

Absolute Refractive Index of a Medium - Definition

The absolute refractive index is defined as the ratio of the speed of light in vacuum and in the given medium. The absolute refractive index should never be less than 1.

((Mark me as a Brainliest pleeeeease))

Answer 2

Answer:

The ratio between the speed of light in medium to speed in a vacuum is the refractive index. When light travels in medium other than the vacuum, the atoms of that medium continually absorb and re-emit the particles of light, slowing down the speed light. In this article, let us discuss the refractive index of water and various mediums.
