After tracing the path of a ray of light through a glass prism a student marked the angle of incidence (∠i), angle of refraction (∠r) angle of emergence (∠e) and the angle of deviation (∠D) as shown in the diagram. The correctly marked angles are :
(A) ∠i and ∠r
(B) ∠i and ∠e
(C) ∠i, ∠e and ∠D
(D) ∠i, ∠r and ∠e

उत्तर
In the given diagram, the angle of incidence (∠i) and the angle of emergence (∠e) have been correctly marked.
Hence, the correct option is B.
Disclaimer: In the question paper the angle of emergence ∠e is drawn incorrectly as it is shown between the normal and the surface of the prism.
