Question

A convex lens is made up of two different materials. How many of images does it form? Explain within a neat ray

diagram.​

Answer 1

Answer:

1. given convex lens is made up of two different materials

2. two different materials have two different refractive indices n1,n2,n3

3. so the given lens have two different focal lengths

4. hence it forms two images

for the ray diagram. you should just draw a biconvex lens and divide it into two halves by drawing a line in the middle. and  shade the two halves with different colour

Explanation:

Answer 2

A lens made of three different materials of refractive indices say n1, n2. These two materials will have two different refractive indices. Thus for a given object it forms two images.
