A 38.0-cm-focal-length converging lens is 26.0 cm behind a diverging lens. Parallel light strikes the diverging lens. After passing through the converging lens, the light is again parallel.
What is the focal length of the diverging lens? Follow the sign conventions. [Hint: first draw a ray diagram.]
