Question
The point on which a parallel beam of light rays parallel to the principal axis converge after reflection from a concave mirror is called its ____.
- Center of curvature

- Aperture
Hint:
Principle focus
The correct answer is: Principal focus
principle focus of the mirror is defined as a point where all paraxial rays intersect after reflection from the mirror.
The rays coming parallel to the principal axis of concave mirror converge to a point.
