If .imuj represnts the refractive index ...

If `._imu_j` represnts the refractive index when a ray of light goes from medium i to j, then the product `._2mu_1xx._1mu_3xx._3mu_4` is equal to

A

`._3mu_1`

B

`._3mu_2`

C

`._2mu_3`

D

`._2mu_4`

Text Solution

Verified by Experts

The correct Answer is:
D
`._2mu_1xx._1mu_3xx._3mu_4=(mu_1)/(mu_2)xx(mu_3)/(mu_1)xx(mu_4)/(mu_3)=(mu_4)/(mu_2)=._2mu_4`
