Question

Define absolute refractive index? What is the relation between the relative refractive index between two media and the absolute refractive index of the media?​

Answer 1

Answer:

Absolute refractive index is the ratio of speed of light in air and speed of light in other medium.

Relative Refractive Index of medium 1 with respect to 2 = Speed of light in medium 2\ Speed of light in medium 1

Absolute Refractive Index of medium = Speed of light in air\ Speed of light in medium
