... placed at x = −30 cm. What is the x position of the final image for light going through the two lenses? Answer: −6 cm Solution: In this problem p1 = 30 cm so that i1 = 7.5 cm. Because the lenses are 12 cm apart this means that p2 = 4.5cm and consequently i2 = −18 cm. Since the second lens is located ...
