Question

A student traces the path of a ray of white light through a rectangular glass slab and marks, the angles of incidence (∠i) , refraction (∠r) and emergence (∠e) as shown. Which angle or angles has he not marked correctly?

(A) ∠i only

(B) ∠i and ∠r

(C) ∠i and ∠e

(D) ∠r and ∠e

Solution

Incident and emergent angles are measured from the normal of the plane.

The Correct Answer is C
