A student traces the path of a ray of light through a rectangular glass slab for the different values of angle of incidence. He observes all possible precautions at each step of the experiment. At the end of the experiment, on analysing the measurements, which of the following conclusions is he likely to draw?
(A) ∠i = ∠e < ∠r
(B) ∠i < ∠e < ∠r
(C) ∠i > ∠e > ∠r
(D) ∠i = ∠e > ∠r

(D) ∠i = ∠e > ∠r

Explanation:

When light is refracted through a glass slab, angle of incidence = angle of emergence. So ∠i = ∠e >. The light passes from rarer medium (air) to the denser medium (glass). So the light ray will bend towards the normal. Hence angle of refraction will be less than the angle of incidence or angle of emergence.

Option D is the answer. ∠i = ∠e > ∠r
