Chapter 34, Problem 107(choose chapter or problem)
A fruit fly of height H sits in front of lens 1 on the central axis through the lens. The lens forms an image of the fly at a distance d 20 cm from the fly; the image has the flys orientation and height HI 2.0H. What are (a) the focal length f1 of the lens and (b) the object distance p1 of the fly? The fly then leaves lens 1 and sits in front of lens 2, which also forms an image at d 20 cm that has the same orientation as the fly, but now HI 0.50H. What are (c) f2 and (d) p2? 108
