Use the worked example above to help you solve this problem. Two converging lenses are placed d2 = 23.4 cm apart, as shown in figure a, with an object d1 = 35.1 cm in front of lens 1 on the left:
(a) If lens 1 has a focal length of f1 = 11.7 cm, locate the image formed by this lens and determine its magnification.
q = cm
M =
(b) If lens 2 on the right has a focal length of f2 = 23.4 cm, locate the image formed and find the total magnification of the system.
q = cm
M =
EXERCISE
If the two lenses in the figure are separated by 11.7 cm, locate the final image and find the magnification of the system. [Hint: The object for the second lens is virtual!] (Use the necessary information from the Practice It portion of the problem.)
q = cm
M =
