Answer» (i) 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) (ii) ‘Reversed’.

Answer»

(i) 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)

(ii) ‘Reversed’.
