In the figure below, stick figure O (the object) stands on the common central axis of two thin, symmetric lenses, which are mounted in the boxed regions.
Lens 1 (mounted in box 1) is a converging lens, O is at object distancep1 = 4.00 cm, and the distance between the lens and its focal point is 9.00 cm. Lens 2 (box 2) is a diverging lens at distance d = 14.0 cm, and the distance between the lens and its focal point is 9.00 cm. What is the overall magnification of the system?
