In the diagram shown, a ray of light is incident on the interface between 1 and 2 at angle slightly greater than critical angle. The light surfers total internal reflection at this interface. After that the light ray falls at the interface of 1 and 3, and again it suffers total internal reflection. Which of the following relations should hold true?

A

`mu_(1) gt mu_(2) lt mu_(3)`

B

`mu_(1)^(2)-mu_(2)^(2) gt mu_(3)^(2)`

C

`mu_(1)^(2)-mu_(3)^(2) gt mu_(2)^(2)`

D

`mu_(1)^(2)+mu_(2)^(2) gt mu_(3)^(2)`

In the diagram shown, light is incident on the interface between media 1 (refractive index n_(1) ) and 2 (refractive index n_(2) ) at angle slightly greater than the critical angle, and is totally reflected. The light is then also totally reflected at the interface between media 1 and 3 (refractive index n_(3) ), after which it travels in a direction opposite to its initial direction, The media must have a refractive indices such that. .
