A converging lens is one which

A converging lens (B) is one that collects rays of light. Also known as a convex lens, it is thicker at the center than at the edges. When parallel rays of light pass through a converging lens, they are refracted and converge to a focal point on the opposite side of the lens. This focal point is where the lens forms a real or virtual image, depending on the location of the object relative to the focal point and the lens. A real image is formed when light rays actually converge at a point and can be projected onto a screen, whereas a virtual image appears to be located at the focal point but cannot be projected. The ability of a converging lens to collect and focus light rays makes it useful in applications such as cameras, magnifying glasses, and corrective lenses for vision correction, where forming clear images or focusing light is essential.
