A lens system consists of two lenses, one is converging and the other is a diverging lens. A screen is placed 32 cm to the right of the converging lens. The object is placed 18 cm to the left of the diverging lens. Lens separation is 34 cm. A real image is formed on the screen. Focal length of the converging lens is 22cm.
a) Find the focal length of the diverging lens?
b) find the magnification of the image?
