Questions
A plot of angle of deviation () versus angle of incidence (i) for a triangular prism is shown below. The angle of incidence for which the light ray travels parallel to the base is
detailed solution
Correct option is C
For light to travel parallel to the base of prism, it should be a minimum deviation condition. For minimum deviation of δ = 400 from graph, i = e = 450.Talk to our academic expert!
