Convex Lens is Converging
The convex lens is called a converging lens because it refracts the rays towards the principal axis so it collects light rays falling on it. This lens can converge a beam of parallel rays of light that is coming from outside and focus it on a point on the other side of the lens. Convex And Concave Lenses Physics Concepts Physics And Mathematics Learn Physics The edges are curved outwards. . If parallel rays of light fall on a concave lens they diverge as they pass through the lens never to meet at a point. Thats why the convex lens is known as a converging lens. Thats why we call them diverging lenses. If the lens is biconvex or plano-convex a collimated beam of light passing through the lens converges to a spot a focus behind the lens. Converging lens also known as a convex lens is thinner at the upper and lower edges and thicker at the center. They are both thicker in middle than near the edges. A convex...
