Question

when a light ray incident normally on a on a glass slab then lateral shift will be a.maximum b. zero c. equal to thickness of glass slab d. based on refractive index of glass slab​

Answer 1

(i) When light rays passed from the rarer medium of air to that of the thick glass slab then the refraction of light will occur and then it will deviate from it's usual way of movement and shift toward the line normal to the glass slab.

(ii) When it leaves the slab it will deviate away from the line normal to that of the glass surface and thus we get the lateral shift in the light ray.
