The factors that affect the lateral displacement of a light as it passes through a rectangular glass slab are: (1) The thickness of the glass slab : The lateral displacement increases with the increase in the thickness of the glass slab. (2) The angle of incidence : It increases with the increase in the angle of incidence. (3) The refractive index of glass : The wavelength of light used. (It is more for violet light than for the red light.) (any one)
