Question

In your laboratory, you trace the path of light rays through a glass slab for different values of angle of incidence (∠i) and in each case, you measure the value of the corresponding angle of refraction (∠r) and angle of emergence (∠e). On the basis of your observations, your correct conclusion is that(a) ∠i is more than ∠r but nearly equal to ∠e(b) ∠i is less than ∠r but nearly equal to ∠e(c) ∠i is more than ∠e but nearly equal to ∠r(d) ∠i is less than ∠r but nearly equal to ∠r
