Question

if the refractive index of second medium with respect to first medium is 2 n 1 and that of the third medium with respect to second medium is 3 n 2 what and how much is 3n1 ​

Answer 1

Answer:

if the refractive index of second medium with respect to first medium is 2 and 1 and that of III medium with respect to second medium is 3 and 2.

Explanation: because It is defined as n=c/v, where c is the speed of light in vacuum and v is the phase velocity of light in the medium.

Answer 2

Answer:

3n1 =n3 upon n1

Explanation:

2n1=n2 upon n1 .......(1)

3n2=n3upon n2......( 2) multiple 1 and 2 2n1×n2=n2 upon n1× n3upon n2. 3n1=n3 upon n1
