Question

A ray PQ incident normally on the refracting face BA is refracted in the prism BAC made of material of refractive index 1.5. Complete the path of ray through the prism. From which face will the ray emerge? Justify your answer.

Answer 1

Here,

`sin i_c=2/3=0.66`

`=>sin 30^0=0.5`

i_c > 30⁰

Thus, here light will emerge out from face AC.
