Answer
(i) The ray of light incident normally on a plane glass slab passes undeviated, ( i.e. such a ray suffers no bending at the surface). Thus, if angle of incidence ∠i = 0°, then the angle of refraction ∠r = 0°.
(ii) In the case when ray of light is incident normally on a plane glass slab, it passes undeviated. Hence, the angle of deviation is 0°.
