Chapter 36 377 P36.74 (a) Start with the second lens: This lens must form a virtual image located 19.0 cm to the left of it (i.e., q 2 19 0 =− . cm ). The required object distance for this lens is then p qf 2 22 19 0 20 0 19 0 20 0 380 39 0 = = −− = .. . cm cm cm cm cm a fa f . The image formed by the first lens serves as the object for the second lens. Therefore, the image distance for the first lens is qp 12 50 0 50 0 380 1570 =−= cm cm cm 39.0 cm 39.0 .
