Focal point a diverging mirror that always produces a virtual image 4. The plus sign indicates that the focal point is real or the rays pass through the point. Imp Concave Vs Convex And Reflective Mirror Vs Refractive Lens Physics Concepts Physics And Mathematics Mirrors And Lenses Center of Curvature C. . A concave lens is one. The images formed from a plane mirror are the reflected images in their normal proportions but reversed from left to right. Find the nature position and size of the image. A magnified or virtual image is formed when the object is placed very close to the concave mirror. It is the effective diameter of the spherical mirror. However for people dealing with hypermetropia a converging lens convex lens is used which we will discuss in this article. Concave mirrors are commonly used as shaving mirrors or by dentists and even in telescopes. We know that a cut-out of a reflective sphere is
