What type of lens is a magnifying glass? a) converging d) cylindrical b) diverging e) plain c) spherical

Short Answer

Expert verified
Answer: A magnifying glass uses a converging lens (convex lens).

Step by step solution

01

Understanding a Magnifying Glass

A magnifying glass is an optical device that works using a convex lens to form a magnified image of an object. It is typically used for reading small texts, examining objects up close, or for the visually impaired. The lens helps in enlarging images by bending light rays that pass through it so that they converge at the focal point.
02

Identifying the Correct Lens Type

Given the properties of a magnifying glass, we can eliminate some options that don't fit these characteristics: a) Converging - A converging lens bends light rays to bring them to a single focal point, forming a magnified image. It is also known as a convex lens. d) Cylindrical - Cylindrical lenses have a curvature in only one plane. They do not serve the purpose of magnifying objects like magnifying glasses do. b) Diverging - A diverging lens, or concave lens, spreads out light rays, making objects appear smaller, which is not the desired purpose of a magnifying glass. e) Plain - A plain lens does not have any curvature, so it does not magnify or minimize images. c) Spherical - A spherical lens has a constant curvature throughout its surface, which could be converging (convex) or diverging (concave) in nature.
03

Selecting the Correct Lens Type

Among the given options, we can conclude that a magnifying glass is a type of: a) Converging lens (convex lens), as it magnifies objects by bending light rays towards a single focal point. This is the optimal lens type for the purpose of a magnifying glass.
