Two systems are formed from a converging lens and a diverging lens, as shown in parts a and b of the drawing. (The point labeled "Fconverging" is the focal point of the converging lens.) An object is placed inside the focal point of lens 1 at a distance of 6.30cm to the left of lens 1. The focal lengths of the converging and diverging lenses are 15.00 and -20.0cm respectively. The distance among the lenses is 50.0 cm. Decide the final image distance for all system, measured with respect to lens 2.
