Can graphically locate the image of any object with a ray diagram. Trace rays following the next rules from the tip of an object and find an intersection point. Any two of them can find an image 1. A ray that is initially parallel to the central axis reflects through the focal point 2. A ray that reflects from the mirror after passing through the focal point emerges parallel to the central axis 3. A ray that reflects from the mirror after passing through the center of curvature Creturns along itself 4. A ray that reflects from the mirror at point is reflected symmetrically about that axis. Let F_1 be the first focal point, and F_2 be the far one. For each of the following draw the final image using ray tracing 1. A ray initially parallel to the central axis of the lens will pass thorugh focal point F_2 2. A ray that initially passes through focal point F 1 will emergy from the lens parallel to the central axis 3. A ray that is initially directed toward the center of a lens will emerge with no change in direction. (nearly parall
