Reflection of Light is the process of sending back the light rays, which falls on the surface of an object. The image formed due to the reflection of an object on a plane mirror is at different places. All the light rays after passing through the concave lens diverge. And when produced backward appear to meet at a point on the principal axis of the lens. This point is known as the principal focus of a concave lens. Thus refracted rays appear to diverge from the focus. A concave lens is opposite to convex lens. Let’s watch the video to know more.
