Question

What is absolute refractive index​

Answer 1

Answer:

absolute refractive index of a medium is defined as the ratio of the velocity of light in a vacuum to the to the velocity of light in the medium

Explanation:

if c is the velocity of light in vacuum and v in the medium

then:

n=c/v

Answer 2

absolute refractive index of a midium is difined as the ratio of the velocity of light in a vocuum to the velocity of light in the midium if c is the velicity of light in vocuum and v in the midium, then v=c/v

the value of absolute refractive index can nerver be less than 1. this is so because light travels with the fastest speed in a vocuum. the lower value of the absolute refractive index indicates a denser medium while a higher value indicates rarer medium.
