Question

The distance between pole and centre of curvature of a spherical mirror is called ________ .​

Answer 1

Explanation:

The distance from the pole to thecenter of curvature is called (no surprise, I hope) the radius ofcurvature (r). The distance from thepole to the focal point is called the focal length (f). The focal length of aspherical mirror is then approximately half its radius of curvature.

Answer 2

Answer:

The distance from the pole to the center of curvature is called (no surprise, I hope) the radius of curvature (r). 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.
