Two converging lenses with focal lengths of 40 cm and 20 cm are
10 cm apart. A 3.0 cm -tall object is 15 cm in front of the 40 cm
-focal-length lens. Calculate the image height.
The figure below shows two converging lenses placed
L1 = 23 cm apart. Their focal lengths are f1
= 10 cm and f2 = 25 cm.

Two converging lenses, with focal lengths f1 = 8 cm and f2 = 15
cm are separated by 30 cm. The lens on the left has a shorter focal
length. An object, 1.5 cm tall, is placed 12 cm to the left of the
combination. (i) Determine the position of the final image relative
to the lens on the right. (ii) Determine the overall magnification
and the height of the final image. (iii) Is the final image real or
virtual?...
