Unformatted text preview: 24. (a) Since this is a converging lens (C) then f > 0, so we should put a plus sign in front of the 10 value given for the focal length. There is not enough information to determine r 1 and r 2 . Eq. 359 gives i = 1 1 f 1 p = 1 1 10 1 20 = +20 cm . There is insucient information for the determination of n . From Eq. 356, m = 20 / 20 = 1 . 0. The image is real (since i > 0) and inverted (since m < 0). The ray diagram would be similar to Fig. 3514(a) in the textbook. (b) Since f > 0, this is a converging lens (C). There is not enough information to determine r 1 and r 2 . Eq. 359 gives i = 1 1 f 1 p = 1 1 10 1 5 = 10 cm . There is insucient information for the determination of n . From Eq. 356, m = ( 10) / 5 = +2 . 0. The image is virtual (since i < 0) and upright (since m > 0). The ray diagram would be similar to Fig. 3514(b) in the textbook....
