Convex lens: A lens with at least one surface that curves outwardly, like a sphere's surface.
A convex lens has at least one surface that bends outward like the exterior of a sphere and is typically composed of glass or transparent plastic.
Given its variety of applications, it is the most widely used lens. A converging lens is another name for a convex lens.
Middle convex lenses are thicker. The lens causes the light rays it receives to concentrate (they converge). A converging lens is one that is convex. The principal focus is the location where refracted light rays converge when parallel light rays travel through a convex lens.
The inverted image formed by the Convex lens:
The opposite of a concave lens is a convex lens. Contrary to concave lenses, light rays converge in convex lenses. In contrast to the concave lens, the convex lens is bigger in the middle and thinner at the edges, therefore it converges the incident rays into its central axis.
Instead of being bent inward, the convex lens' edges are curved outward. The image seems smaller and inverted when the light is extremely focused beyond the focal length of the lens.
A convex lens's opposite side's center of curvature, , creates the image of an object placed in the center of curvature, , of the lens. As seen in the given illustration, the picture that forms is inverted and the same size as the object.
Hence, transparent glass or plastic is used to create convex lenses. At least one of its surfaces must be curved outward like the sphere's outside.
