Lens #1 f = +20 cm 2 O I = O 1 1 1 Lens #2 f = 50 cm 2 F for Lens #2 The ray coming in parallel to the axis reflects out along a line which projects back through one of the focal points of Lens #2, which happens to be at the location of the original object in this particular example. Lens #1 f = +20 cm 2 O I = O 1 1 1 Lens #2 f = 50 cm 2 F for Lens #2 I 2 The final image (seen by an observer to the right of this diagram) forms where the two rays intersect. Lens #1 f = +20 cm 2 O I = O 1 1 1 Lens #2 f = 50 cm 2 F for Lens #2 I 2 The diverging lens (#2) causes the rays of light from Lens #1 to diverge (a little) from their paths toward image #1, so that the final image (#2) forms farther to the right....
