A ray incident at 50° on one refracting surface of a prism of angle 60°, suffers a deviation of 40°. The angle of emergence is:
- A 95°
- B 45°
- C 30°
- D 50°
Answer & Solution
Correct Answer
(D) 50°
Step-by-step Solution
Detailed explanation
\( \delta = i + e - A \) \( 40^\circ = 50^\circ + e - 60^\circ \) \( 40^\circ = e - 10^\circ \) \( e = 50^\circ \)
