Answer 1

Explanation:

Lateral shift for light passing through a rectangular glass slab is maximum for an incidence angle of 90°. Lateral Displacement can be zero in the following case: General formula for Lateral Displacement: t is the lateral Displacement, i is angle of incidence and r is angle of refraction.
