Q. What is magnifying glass used for?

Answer

A magnifying glass, or convex lens, is used to create an enlarged picture of an item. The lens is often fastened to a grippy frame. The sun's rays may be focused with a magnifying glass to create a concentrated hotspot that can be used to start a fire. One of the most often used pieces of lab gear, magnifying glasses are essentially a simplified version of a microscope. By increasing the object's magnification, magnifying glasses allow users to better study its minute details. Most people think that they are the same as loupes, which is not the case.
