Question
For a convex 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
- Joining the focus to the point
- Extending the line joining the focus and the point
Hint:
Extending the line joining g the centre of curvature and the point.
The correct answer is: Extending the line joining the center of curvature and the point
The normal is drawn normal to the tangent at the point of incidence, that is, it is drawn by connecting the mirror's center of curvature to the point of incidence.
