Question

What is differentiate between Relative refractive index & Absolute refractive index..??

Answer 1

Relative refractive index is the refractive index of any medium A ( say water ) with respect to that of any other medium B ( say glass).
Absolute refractive index is refractive index of any medium with respect to AIR or VACUUM.

Answer 2

HEYA...!!!



Relative refractive index : Relative refractive index is the ratio of the speed of light in the medium 1 to the speed of light in medium 2. The value of absolute refractive index may be greater than or less than unity.


Absolute Refractive Index : Absolute refractive index is the ratio of the speed of light in vaccum to the speed of light in the medium. The value of absolute refractive index is greater than unity.



hope it helps :)
