When an object is placed at the proper distance to the left of a converging lens, the image is focused on a screen 30.4 cm to the right of the lens. A diverging lens is now placed 14.9 cm to the right of the converging lens, and it is found that the screen must be moved 19.2 cm farther to the right to obtain a sharp image. What is the focal length of the diverging lens? Express your answer in centimeters.
