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
Solution
The correct sequence of labeling ∠i, ∠e, ∠r and lateral displacement respectively is 1, 3, 2 and 4.
Hence, the correct answer is option (c).
