Chapter 34, Problem 79P

69 through 79 GO 76, 78 SSM 75, 77 More lenses. Object O stands on the central axis of a thin symmetric lens. For this situation, each problem in Table 34-8 refer to (a) the lens type, converging (C) or diverging (D), (b) the focal distance f, (c) the object distance p, (d) the image distance i, and (e) the lateral magnification m. (All distances are in centimeters.) It also refers to whether (f) the image is real (R) or virtual (V), (g) inverted (I) or noninverted (NI) from O, and (h) on the same side of the lens as O or on the opposite side. Fill in the missing information, including the value of m when only an inequality is given. Where only a sign is missing, answer with the sign.
