Activity 1. Use ray diagrams to find the image position and magnification for an object at each of the following distances from a converging lens with a focal length of 20 cm: (a) 20 cm; (b) 15 cm; 2. A beam of parallel rays spreads out after passing through a thin diverging lens, as if the rays all came from a point 40.0 cm from the center of the lens. You want to use this lens to form an erect, virtual image that is the 1/3 height of the object. (a) Where should the object be placed? Where will the image be? (b) Draw a principal- ray diagram.
