Lenses with given radii, Object O stands in front of a thin lens, on the central

Question

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 - 7 ( below ) gives object distance p, index of refraction n of the lent, radius r1 of the nearer lens surface, and radius r2 of the farther lent surface. ( All distances are in centimeters. ) Find ( a ) the the image distance i and ( b ) the lateral magnification m of the object, including signs. Also, determine whether the image is ( c ) real ( enter 1 ) or virtual ( enter 0 ) , ( d ) inverted ( enter 1 ) from object O or non inverted ( enter 0 ) , and ( e ) on the same side of the lens as object O ( enter 1 ) or on the opposite side ( enter 0 ) . TABLE 34.7 Problems 58 through 67: Lenses with Given Radii. See the setup for these problems.

Explanation / Answer

62. (a) Combining Eq. 34-9 and Eq. 34-10 gives i = –9.7 cm. (b) Eq. 34-7 give m = -i / p = +0.54. (c) The fact that the image distance is a negative value means the image is virtual (V). (d) A positive value of magnification means the image is not inverted (NI). (e) The image it is on the same side as the object (see Fig. 34-16).
