How is the focal length of a spherical mirror related to its radius
Advertisements
उत्तर
The distance from the pole to the focal point is called the focal length (f). The focal length of a spherical mirror is then approximately half its radius of curvature.
Focal length = Radius of curvature / 2
Or 2 F = R
