Question

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

Answer 1

b one is the correct answer

Answer 2

B) ∠i and ∠e

Explanation:

The diagram is missing in the question. Please find the attached picture for the diagram. The answer is with respect to the attached picture.

Angle of incidence is correctly marked as ∠i in the given diagram.  

Angle of emergence is correctly marked as ∠e in the given diagram.

So ∠i and ∠e are the correct marked angles Option B is the correct answer.
