A 2.1 cm-tall object stands in front of a converging lens. It is desired that a virtual image 2.3 times larger than the object be formed by the lens. How far from the lens (in cm) must the object be placed to accomplish this task, if the final image is located 14 cm from the lens?

    An object is placed in front of a converging lens in such a position that the lens (f = 14.0 cm) creates a real image located 22.0 cm from the lens. Then, with the object remaining in place, the lens is replaced with another converging lens (f = 15.0 cm). A new, real image is formed. What is the image distance of this new image?
