58 through 67 61 59 Lenses with given radii. An object stands in front of a thin lens, on the central axis. For this situation, each problem in Table 34-7 gives object distance , index of refraction n of the lens, radius of the nearer lens surface, and radius localid="1663061304344" of the farther lens surface. (All distances are in centimeters.) Find (a) the image distance and (b) the lateral magnification of the object, including signs. Also, determine whether the image is (c) real or virtual ,(d) inverted from the object or non-inverted , and (e) on the same side of the lens as object or on the opposite side.

Light travels from point A to B point via reflection at point O on the surface of a mirror. Without using calculus, show that length AOB is a minimum when the angle of incidence is equal to the angle of reflection .

In Fig. 34-38, a beam of parallel light rays from a laser is incident on a solid transparent sphere of an index of refraction n. (a) If a point image is produced at the back of the sphere, what is the index of refraction of the sphere? (b) What index of refraction, if any, will produce a point image at the center of the sphere?
