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 = 21 cm from the fly; the image has the fly's orientation and height H = 2.4 H. What are (a) the focal length f 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 atd = 21 cm that has the same orientation as the fly, but now H = 0.76 H. What are (c) f2 and (d) P2?
