In ray diagrams of concave mirrors where is the image formed? Like we show that in such conditions the image will be formed behind centre of curvature, but centre of curvature is the centre of a spherical mirror, but the concave mirror which we're using is only a part of it. So, how can the image be formed behind centre of curvature. Does it hangs into air? Then where's the screen.
I know it's a foolish doubt but becoming a problem for me.
