Ray Diagrams- Curved Mirrors Rules for locating images formed by mirrors using ray diagrams l. All rays start from the same point on the object. 2. Ray l is drawn from the object parallel to the axis and passes through the focal point after reflection. 3. Ray 2 is drawn from the object through the focal point and is drawn parallel to the axis after reflecting off the mirror. 4. Ray 3 connects the center of curvature and the object. Because this ray passes through the center of curvature it will be perpendicular to the surface of the mirror and will reflect back onto itself. 5. The image is formed where the rays intersect. 6. If the rays never intersect on the front side of the mirror, a virtual image is formed behind the mirror. 7. To locate the virtual image, extend the rays behind the mirror using dashed lines. The image is formed where the lines connect. For each ray diagram determine the following: Is the image real or virtual? Is the image the same size, larger, or smaller than the original image? Is the image erect or inverted
