Convex lenses are also commonly referred to as converging lenses, positive lenses, or bulging lenses. These lenses converge the light rays that pass through them and project them onto a focal point. The opposite of a convex lens is a concave lens, also called a diverging lens or negative lens. Convex lenses are commonly found in cameras, telescopes, and microscopes, and are used to magnify and focus images. They are named for their outwardly bulging shape, which causes light to be bent inward toward the center of the lens. Convex lenses have a wide range of applications in science, engineering, and technology.
