All our life we have known a magnifying glass as a tool for discovering clues. We also have known it to be a tool for enlarging and making things bigger. A magnifying glass is not only used for this it is used for many experiments for example to measure the focal length of a convex lens. A magnifying glass is a double convex or converging lens. A lens is a curved transparent material that bends light. These lenses are used to produce a magnified image of an object. In the magnifying glass's lens there is a line that runs through the center of the lens and perpendicular to its surface it is called the principal axis. All light rays that enter parallel to the principal axis are refracted toward the focus, where they come together or converge. The distance from the focal point to the lens is called the focal length (f). The reciprocal of the focal length is a measure of how strongly an optical system focuses or defocuses light.
