Question

what is refractive index of a medium? explain absolute refractive index and relative refractive index. (marks 3)

Answer 1

Answer:

Relative refractive index: When light travels from one medium to another medium, then the refractive index is known as the relative refractive index.

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

Answer 2

Explanation:

Relative refractive index: When light travels from one medium to another medium, then the refractive index is known as the relative refractive index. Absolute refractive index: When light travels from vacuum to another medium, then the refractive index is known as the absolute refractive index.
