Q.) If the object inside the box was made of a
material with a refractive index less than
1.5 then the :
(a) lateral shift of the rays would have been less.
(b) lateral shift of the rays would have been more.
(c) lateral shift of the rays would remain the same as before.
(d) there is not enough information to comment on any of the above statements
Ans. (a) lateral shift of the rays would have been less.
Explanation: The lateral shift depends on the refractive index of the medium and thickness of the slab. The greater the refractive index of the second medium, greater would light bend and hence greater would be the lateral shift.
