Mirrors and Lenses 287 (b) If 4.00 p = , then and m 1.00 m q = 1.00 m 1 4.00 m 4 q M p = −= = In this case, the image is real, in 4.00 m q = verted, and one-quarter the size of the object If , then and 1.00 m p = 4.00 m 4 1.00 m q M p = = . In this case, the image is real, inverted, mes th and four ti e size of the object 23.39 Since the light rays incident to the first lens are parallel, 1 p = and the thin lens equation gives . The virtual image formed by the first lens serves as the object for the second lens, so 11 10.0 cm qf == 2 30.0 cm p =+ 2 q = 1 40.0 cm q = . If the light rays leaving the second lens are parallel, then and the thin lens equation gives 22 40.0 c fp m . 23.40 With p and , the thin lens equation gives the position of the image formed by the first lens as 1 20.0 cm = 1 25.0 cm f
