Vedclass · Answer

(C) The lens is composed of $3$ different materials,each having a different refractive index. Since the lens is formed by $3$ distinct parts,each part acts as an independent lens with its own focal length. When a point object is placed on the principal axis,light rays passing through each of the $3$ different sections will be refracted differently. Consequently,each section will form an image of the object at a position determined by its specific focal length. Therefore,$3$ distinct images will be formed,one by each section of the lens.

$A$ convex lens is made of $3$ layers of glass of $3$ different materials as shown in the figure. $A$ point object is placed on its axis. The number of images of the object formed is:
