Question

A Convex lens is made up of 4 materials. how many images will it form.​

Answer 1

The given convex lens is made up of five different materials.So they have different refractive indices/ different focal lengths. Hence they form five different images.

Answer 2

A Convex lens made up of 4 materials will form:

• If a lens is constructed out of n different materials with various refractive indices, the lens will produce n separate images for each refractive index.

• Here, the convex lens in question is made up of four distinct materials. As a result, their refractive indices and focus lengths differ. As a result, four distinct images will be formed.
