Answer 1

answer 1
number of images =number of materials
or
answer 2
only one image forms

Answer 2

Answer:

Number of images depends on the number of material is used to make convex lens .

Explanation:

A convex lens is made of different materials  than the number of image formed by the convex lens is depend on the how many different no. of material is used  to make this lens.Because they have  different   focal lengths. Example: Lets take an example suppose a convex lens is made up of 5 different material, then they have 5 different focal lengths

Therefore , 5 images will be formed .

Final answer:

Hence, the no. of material is used  to make convex lens is equal to the number of images will be formed.
