Question

Two-lens systems. The stick figure O (the object) stands on the common central axis of two thin, symmetric lenses. Lens 1 is mounted within the boxed region closer to O, which is at object distance do 1. Lens 2 is mounted within the farther boxed region, at distance d.


The table refers to the focal distances f1 and f2 for lens 1 and lens 2 respectively, the image distance di 2 for the final image produced by lens 2 (the final image produced by the system) and the overall lateral magnification mtot for the system. All distances are in centimeters. Fill in the missing information, including signs.
