An upright object is placed a distance in front of a converging lens equal to twice the focal length (f1) of the lens. On the other side of the lens is a converging mirror of focal length f2 separated from the lens by a distance 2(f1+f2).
A) Find the location, nature, and relative size of the final image, as seen by an eye looking toward the mirror though the lens.
B) Draw the relevant ray diagram.
