Magnifying Glass: A Close-Up View

What type of lens is found in a magnifying glass?

A. Concave lens

B. Convex lens

C. Flat lens

Answer:

B. Convex lens

When using a magnifying glass to closely examine objects like stamp collections, the type of lens found in a magnifying glass is a convex lens. Convex lenses are thicker in the middle and thinner at the edges, causing light rays passing through them to converge. This convergence creates a magnified (larger) image of the object being observed, making it easier to see details that may not be visible to the naked eye.

Convex lenses are commonly used in magnifying glasses, microscopes, and cameras to produce enlarged images of objects. By understanding the optical properties of convex lenses, we can appreciate how they help us to see things more clearly and in greater detail.

Next time you use a magnifying glass, remember that it is the convex lens inside that is responsible for making those tiny details larger than life!
