Question
A ray incident at an angle 53∘ on a prism and emerges at an angle of 37∘ as shown in figure. If the angle of incidence is made 50∘ then possible value of the angle of emergence is
Answer: Option D
:
D
Deviation produce by the prism isδ=i+e–A=53∘+37∘–A=90∘–A
For angle of incidence 50∘ angle of emergence will be grater than 37∘ and also
i + e < 90∘
