Redraw the following diagram on your answer-sheet and show the path of the reflected ray. Also mark the angle of incidence () and the angle of reflection () on the diagram.
Answer
The mirror is convex (F and C lie behind it), and the incident ray is directed towards F. After reflection the ray travels back parallel to the principal axis. The normal at the point of incidence is the line joining C to that point, produced in front of the mirror; is the angle between the incident ray and this normal, the angle between the normal and the reflected ray, and (see the figure).
