A student traces the path of a ray of light passing through rectangular glass slab for three different values of angle of incidence (∠i), namely 30°, 45°, 60°. He produces the incident ray and measures the perpendicular distance, l, between the produced incident ray and the emergent ray He will observe that (1) ‘l’ keeps on increasing with increase in angle of incidence (2) ‘l’ keeps on decreasing with increase in angle of incidence (3) ‘l’ remains the same with three angles of incidence (4) ‘l’ is maximum for ∠i = 45° and is less than this value both for ∠i = 30° and for ∠i = 60°

Answer: (1) The perpendicular distance between the produced incident ray and the emergent ray is known as lateral shift. Lateral shift is given by the relation Where, t = Thickness of the slab i = Angle of incidence r =Angle of reflection It is evident from the relation that as the angle of incidence increases, lateral shift also increases.
