A converging lens (f = 14.2 cm) is located 23.2 cm to the left of a diverging lens (f = -4.59 cm). A postage stamp is placed 37.1 cm to the left of the converging lens. (a) Locate the final image of the stamp relative to the diverging lens. (b) Find the overall magnification.
We have lens formula as
For converging lense f = 14.2 and u = -37.1 cm
Now object distance for the diverging lens is 23.2 -23.0 = 0.2 cm
so image will form at a distance of 0.19 cm left to the diverging lens.
So total magnification will be
