Question
For a concave mirror, the normal line at a point on the mirror is drawn by _____.
- Joining the center of curvature to the point
- Extending the line joining the center of curvature and the point

- Extending the line joining the focus and the point
Hint:
Joining the centre of curvature to the point
The correct answer is: Joining the center of curvature to the point
in a concave mirror, normal drawn on any point on the mirror passes through the center of curvature.
