what is the graph between magnification and image distance for a convex lens..and how can we find the focal length for the lens using the graph? Ans) The distance between the lens and the screen was the focal length f of the lens and graph between magnification and image distace is a straight line i think because image distace is proportional to the magnification( i.e m=v/u) here v=image distace
