Question
The distance between the center of curvature and the pole of a spherical mirror is called its ____.
- Center of curvature
- Radius of curvature
- Focal length
- Aperture
Hint:
Radius of curvature
The correct answer is: Radius of curvature
pole is a point on the spherical mirror. Centre of curvature is the center of the sphere of which the mirror forms a part. Hence, the distance between them is the radius of curvature.
