Name the type of lens that can be used as a magnifying glass. Give reason$(s)$ and draw a ray diagram to support your answer.
(N/A) convex lens is used as a magnifying glass.
Reason: When an object is placed between the optical center $(O)$ and the principal focus $(F_1)$ of a convex lens,it forms a virtual,erect,and magnified image on the same side of the lens as the object.
Ray Diagram: The diagram shows the object $AB$ placed between $O$ and $F_1$,resulting in a virtual,magnified image $A'B'$ formed behind the object.
