Which of the following relation is correct for relative refractive index ?

A

`""^1n_2=""^1n_2xx""^3n_2`

B

`""^1n_3xx""^3n_2=""^2n_1`

C

`""^1n_3xx""^3n_1=0`

D

`(""^1n_3)/(""^2n_3)=""^1n_2`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
`(""^1n_3)/(""^2n_3)=""^1n_3xx""^3n_2`
`=(n_1)/(n_3)xx(n_3)/(n_2)=(n_1)/(n_2)=""^1n_2`
