You have a concave (diverging) lens with a −30 cm focal length. The magnification produced by the lens for a particular object distance is m = 1/2 and you wish to decrease the magnification to m = 1/8. Determine the distance and direction (away from or closer to the lens) through which the object must be moved in order to accomplish this.

    A concave lens refracts parallel rays in such a way that they are bent away from the axis of the lens. For this reason, a concave lens is referred to as a diverging lens. Part A Consider the following diagrams, where F represents the focal point of a concave lens. In these diagrams, the image formed by the lens is obtained using the ray tracing technique. Which diagrams are accurate?(Figure 1) (Figure 2) (Figure 3) (Figure 4) Type A if...
