1. The problem is to understand which rays to draw when an object is placed exactly at the center of curvature (point C) of a convex mirror. 2. Important to know: For a convex mirror, the center of curvature (C) is behind the mirror, and the mirror always forms virtual, upright, and diminished images. 3. When the object is at point C, draw these principal rays: - Ray 1: Draw a ray from the top of the object parallel to the principal axis. After reflection, this ray appears to diverge from the focal point (F) behind the mirror. - Ray 2: Draw a ray directed towards the center of curvature (C) behind the mirror. This ray reflects back on itself because it strikes the mirror perpendicularly. - Ray 3: Draw a ray aimed at the focal point (F) behind the mirror. After reflection, this ray travels parallel to the principal axis. 4. The image is formed where the reflected rays appear to diverge from behind the mirror. For a convex mirror, the image is always virtual, upright, and smaller than the object. 5. Summary: Draw the three rays as described, and the image will appear between the focal point (F) and the mirror, smaller and upright. This method helps you accurately construct the ray diagram for an object at point C in a convex mirror.
