Question
A normal line to the reflecting surface of a convex mirror can be drawn easily by _____.
- Using a protractor to draw a line at 90-degree angle with the surface
- Using a compass, a ruler, and a pencil to draw a line at 90-degree angle with the surface
- Joining the center of curvature and the point considered
- None of the above
Hint:
Joining the center of curvature and the point considered
The correct answer is: Joining the center of curvature and the point considered
The perpendicular to the point on the mirror gives the normal passing through the center of curvature
