Object O1 is 14.7 cm to the left of a converging lens with a 10.8-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
(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? real and inverted real and upright virtual and upright virtual and inverted.
