An object is placed 7.5 cm in front of a converging lens with a focal length f1 = 2.5 cm. On the other side of the lens is a concave mirror of focal length f2 = 1.5 cm. The mirror is 5.0 cm from the lens. Light from the object passes rightward through the lens, reflects from the mirror, passes leftward through the lens, and forms a final image of the object. ksid tet to What is the distance between...
