7.8 A thin lens with a focal length of 9.0 cm and an aperture of 6.0 cm is located 4.50 cm in front of a diverging lens with a focal length of -8.0 cm and an aperture of 6.0 cm. For light incident on the first lens parallel to the axis calculate the position and size of (a) the entrance pupil and (b) the exit pupil. (c) Solve graphically. Find (d) the focal point of the system, (e) the principal point to which it is measured, and (f) the focal length.
