A coin is placed 26 cm in front of a two-lens system. Lens 1 (nearer the coin) has focal length f1 = +17 cm, lens 2 has f2 = +22.8 cm, and the lens separation is d = 44 cm. For the image produced by lens 2, what are (a) the image distance i2 (including sign) and (b) the overall lateral magnification, (c) the image type (real or virtual), and (d) the image orientation (inverted relative to the coin or not inverted)?
