Walker, Halliday & Resnick — Images: Problem 70 through 79

70 through 79 Lenses with given radii. Object O stands in front of a thin lens, on the central axis. For this situation, each problem in Table 34-8 gives object distance p, index of refraction n of the lens, radius r1 of the nearer lens surface, and radius r2 of the farther lens surface. (All distances are in centimeters.) Find (a) the image distance i and (b) the lateral magnification m of the object, including signs. Also, determine whether the image is (c) real (R) or virtual (V), (d) inverted (I) from object O or noninverted (NI), and (e) on the same side of the lens as object O or on the opposite side.
