Vedclass · Answer

(B) By observing the figure,we can see that the incident light beams entering through holes $A$ and $B$ emerge through holes $C$ and $D$ respectively,without any change in their direction or convergence/divergence. This indicates that the light rays have undergone lateral displacement,which is a characteristic property of a rectangular glass slab. $A$ convex lens would converge the rays,a concave lens would diverge them,and a prism would deviate the rays at an angle. Therefore,a rectangular glass slab is the correct component inside the box.

Beams of light are incident through the holes $A$ and $B$ and emerge out of the box through the holes $C$ and $D$ respectively,as shown in the figure. Which of the following could be inside the box?
