A ray OP of monochromatic light is incident on the face AB of prism ABCD mear vertex B at an incident angle of `60degree` (see figure). If the refractive index of the material of the prism is `sqrt3`, which of the following is (are) are correct? `

A

The ray gets totally internally reflected at face CD

B

The ray comes out through face AD

C

The angle between the incident ray and the emergetn ray is `90^(@)`

D

The anglel between the incidnet ray and the emergent ray is `120^(@)`

Text Solution

Verified by Experts

The correct Answer is:
a.,b.,c.
Using Snell's law, `"sin"^(-1)(1)/(sqrt(3)) lt "sin"^(-1)(1)/(sqrt(2))`
Net deviation is `90^(@)`
