Draw a ray diagram to show the formation of a real magnified image by a convex lens. (In your sketch the position of object and image with respect to the principal focus of lens should be shown (clearly).

a) Explain what is meant by a virtual, magnified image. b) Draw a ray diagram to show the formation of a virtual magnified image of an object by a convex lens. In your diagram, the position of object and image with respect to the principle focus should be shown clearly. c) Three convex lenses are available having focal lengths 4cm, 40 cm and 4 m respectively. Which one would you choose as a magnifiying glass and why?
