Vedclass · Answer

(B) The lens is composed of three distinct horizontal sections,each made of a different material with a different refractive index.Each section acts as an independent lens with its own focal length,determined by the lens maker's formula: $\frac{1}{f} = (\mu - 1) (\frac{1}{R_1} - \frac{1}{R_2})$.Since there are $3$ different materials,there are $3$ different focal lengths.When a point object is placed on the principal axis,each section forms an image at a position corresponding to its specific focal length.Therefore,the total number of images formed is $3$.

$A$ convex lens is made up of three different materials as shown in the figure. For a point object placed on its axis,the number of images formed is:
