In the figure shown at the right, point O is a source of light. Two rays from O are shown reflecting from a curved mirrorand crossing each other at the point marked C. (The mirror is a part of a sphere but the curvature is not drawn to scale) On the figure, find the focus of the mirror by drawing appropriate rays. Explain why you drew the lines you did.
