Combination of lenses: Consider a magnifying lens in which light passes through first a diverging lens, with f1 = -10 mm, and then a converging lens, with f2 = 20 mm, with the two lenses spaced 12 mm apart. Suppose you use this to view a small bug 20 mm from the diverging lens, while looking through the converging lens. Where is the bug's image and what is the magnification?
