Question

Define absolute refraction index of a medium

Answer 1

Answer:

Dear,

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.

Let c be the speed of light in vacuum and v in the given medium, then absolute refractive index is given as:

n=frac{c}{v}

Explanation:

Answer 2

Explanation:

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. The value of the absolute refractive index can never be less than 1.
