Answer
(a) The perpendicular shift in the path of the incident ray, while emerging out from an optical slab is called lateral displacement.
(b) The three factors that determine the lateral displacement are:
(i) thickness of the optical slab
(ii) refractive index of the material of the slab
(iii) wavelength of light.
