1. The problem statement, all variables and given/known data The object in Figure P23.50 is midway between the lens and the mirror. The mirror's radius of curvature is 20.4 cm, and the lens has a focal length of -16.9 cm. http://www.webassign.net/sf5/p23_54.gif Figure P23.50 A. Considering only the light that leaves the object and travels first toward the mirror, locate the final image formed by this system. B.What is the overall magnification of the image? 2. Relevant equations 1/p+ 1/q = 2/R and M=-q/p 3. The attempt at a solution I tried the problem this way 1/12.5 +1/q = 2/20.4 so q=55.43 then I found M for the mirror 55.43/12.5 = 4.43 then I found q lens =25-55.43= -30.43 and M = -(-16.9/-30.43) = 0.56 So final image is 30.43-25= 5.43cm behind the mirror and M tot=4.43*0.56= 2.5 These are not the right answers though. Can anyone help?
