The relation between the focal length and the radius of curvature of a spherical mirror is f = R / 2
option 3
Explanation:
- the radius of curvature is usually twice the focal length of a spherical mirror. As a result of this the diameter of the spherical mirror is 4 times the focus of the spherical mirror.
- The diameter of a spherical mirror means the diameter of the circle of which the spherical mirror is a part. It has no relationship with the the aperture of the mirror if the mirror is not perfectly semicircular in nature.
