This has solution pp L L2 4f L (0:44 m) (0:44 m) 4(0:11 m)(0:44 m) o = = = 0:22 m: 22 There is only one solution to this problem, but sometimes there are two, and other times there are none!E40-30 (a) Real images (from real objects) are only produced by converging lenses. (b) Since hi = h0=2, then i = o=2.
