Question

define absolute refraction 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 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

$\huge\underline\mathfrak\orange{ANSWER}$

$\large\mathbb\red{ABSOLUTE\:REFRACTIVE\:INDEX}$

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.

When light travels from vacuum to another medium, then the refractive index is known as the absolute refractive index.
