Question

A student very cautiously traces the path of a ray through a glass slab for different values of the angle of incidence (∠i). He then measures the corresponding values of the angle of refraction (​∠r) and the angle of emergence (​∠e) for every value of the angle of incidence. On analysing these measurements of angles, his conclusion would be
(A) ∠i > ​∠r > ​∠e
(B) ​∠i = ​∠e > ​∠r
(C) ​∠i < ​∠r < ​∠e
(D) ​∠i = ​∠e < ​∠r

Answer 1
