14) Consider a two thin lens system: The left lens has a focal length of $f_1$ = 50 cm, while the lens on the right has a
focal length of $f_2$ = -50 cm The lenses are separated by 100 cm. An object of height 20 cm is positioned 75
cm to the left of the converging lens, i.e. $s_1$ = 75 cm
a. What is the image distance associated with the given $s_1$, i.e. what is $s_1'$?
b. Is the image formed by the first lens real or virtual? Upright or inverted?
c. What is the object distance for the diverging lens, i.e. what is $s_2$?
d. What is the image distance associated with the given $s_2$, i.e. what is $s_2'$?
e. Is the image formed by the second lens real or virtual? Upright or inverted?
f. (3 pts EC) Draw a diagram of your interpretation of the problem, and include your results,
9. (3 pts EC) What is the total magnification for the two-lens system, and what is $y_2'$.
