a) A converging lens with a focal length of 15cm has an object 5cm tall placed 40cm to the left of it. To the right, 30 cm away, is a converging lens of focal length 10cm. use the thin lens and magnification formulae to locate the finale image. Find its magnification.
b) Repeat part A for a -10cm diverging lens.
1/f = 1/di + 1/do
m = -(di/do)
m = hi/ho
