the ray diagram for concave mirror and that of convex lens are same and of convex mirror and that of concave lens are same. why?

Open in App

Solution

There is no comparison between the two cases as they are entirely different cases.However There is similarity between the diagrams because of the nature of the images formed by them in general. That is convex lens and concave mirror form real inverted images in general.
