Exercise 28

A leaf of length h is positioned 71.0 cm in front of a converging lens with a focal length of 39.0 cm. An observer views the image of the leaf from a position 1.26 m behind the lens, as shown in Figure P25.23. (a) What is the magnitude of the lateral magnification (the ratio of the image size to the object size) produced by the lens (b) What angular magnification is achieved by viewing the image of the leaf rather than viewing the leaf directly
