consider a system of two lenses. The first lens is a converging lens with a focal length f1=21.4 cm. The second lens is a diverging lens with focal length f2=-34.4 cm. The center of the second lens is d=80.0 cm to the right of the center of the first lens. These lenses produce an image of the object
a) Where is the image produced by the second lens with respect to the center of the lens?
b) is the image real or virtual?
c) what is the magnification?
