Object O1 is 15.2 cm to the left of a converging lens with a 11.8-cm focal length. A second lens is positioned 10.0 cm to the right of the first lens and is observed to form a virtual image at the position of the original object O1.
(a) What is the focal length of the second lens?
=_____ cm
(b) What is the overall magnification of this system?
=_______
(c) What is the nature (i.e., real or virtual, upright or inverted) of the final image?
