Document Summary

Dividing (1) by (2) f f nm. 4 (1. 25 nm) f = f. Problem 2: for the plane side, r1 = . For the curvature r2 of the convex side, The situtaion is shwon in the gure (1) below: L = so1 + si1 = so2 + si2. Because the lens equation can be satis ed the second time by simply interchanging object and image distances, so2 = si1; si2 = so1 (6) L + d = so2 + si1 = 2so2 where i used the eq. (6). L d = so2 si1 + si2 + si2 = 2si2. University of toronto where i again used the eq. (6). D2 = 4so1so2 = 4f l f = Given l = 20 cm and d = 10 cm f = 3. 75 cm. 5(cid:19) = nl = 0. 66 + 1 = 1. 66 nl = 1. 66. b). = f = so1si1 so1 + si1 (7)
