Question

A student has traced the path of a ray of light through a glass slab as follows. If you are asked to label 1, 2, 3 and 4, the correct sequencing of labeling ∠i, ∠e, ∠r and lateral displacement respectively is
(a) 2, 1, 3, 4
(b) 1, 2, 3, 4
(c) 1, 3, 2, 4
(d) 1, 3, 4, 2

Answer 1

Answer:

c one is the correct answer

Answer 2

(c) 1, 3, 2, 4.

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.

The correct sequence of labeling is ∠i (angle of incidence), ∠e (angle of emergence),  ∠r (angle of refraction) and lateral displacement is 1, 3, 2 and 4 respectively in the given diagram.

So option C is the correct answer.
