Questions
An equilateral prism ABC is placed in air with its base side BC lying horizontally along x-axis. A light ray is incident at a point P on face AB of the prism.
If for the prism is , then net deviation of the ray as it emerges out of the prism is
detailed solution
Correct option is A
For μ=32, total internal reflection takes place at AC. From geometry, it in clear that ray in perpendicular incident on BC, so net deviation = 180o-120o=60o, only at AC.Talk to our academic expert!
