12. An object is placed to the left of a lens, and a real image is formed to the right of the lens. The image is inverted relative to the object and is one-half the size of the object. The distance between the object and the image is 70.9 cm. (a) How far from the lens is the object? d. (b) What is the focal length of the lens? 13. As an aid in working this problem, consult Concept Simulation 26.3. A converging lens has a focal length of 88.50 cm. A 13.0 cm tall object is located 170.0 cm in front of this lens. (a) What is the image distance? cm (b) is the image real or virtual? real virtual (C) What is the image height? Be sure to include proper algebraic sign. cm 14. A converging lens (f = 13.0 cm) is held 8.70 cm in front of a newspaper, the print size of which has a height of 2.08 mm. (a) Find the image distance (in cm), d = cm (b) The height (in mm) of the magnified print. h = mm
