WebNov 6, 2024 · 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. The concave lens is called diverging lens because it refracts the rays away from the principal axis, so it separates light rays falling on it. Lenses WebConverging: Biconvex, planoconvex, and positive meniscus lenses focus light. Diverging: Biconcave, planoconcave, and negative meniscus lenses diverge light. Meniscus lenses are the type used in eyeglass and contact lenses. Positive meniscus lenses are thicker at the center than the edges.
