A ray of light passes through four transparent media with refractive index µ1, µ2, µ3 and µ4 shown in figure. The surfaces of all media are parallel. If BC and DE are parallel, we must have
|
µ1 = µ4 µ2 = µ3 µ2 = µ4 µ1 = µ2 |
µ2 = µ4 |
If light rays are parallel then refractive index of the two mediums are parallel. $ \mu_2 = \mu_4$ |
