Question

what is lateral displacement?​

Answer 1

Lateral Displacement is the perpendicular distance between the emergent ray from a glass slab and the incident ray produced forward.

It depends upon the thickness of the glass slab, the angle of incidence and angle of refraction and since these two angles are related by refractive index, we can equally say that the lateral displacement depends upon the refraction index.

Answer 2

Answer:

Lateral Displacement. The perpendicular distance between the incident ray and the emergent ray is defined as lateral shift. This shift depends upon the angle of incidence, the angle of refraction and the thickness of the medium.
