Question

relationship between radius of curvature and the focal length​

Answer 1

Answer:

radius of curvature = f/2

Answer 2

The radius of curvature (r) is the radius of the lens that forms a complete sphere. ... The focal length (f) of a lens is the distance between the center of the lens and the point at which the reflected light, of a beam of light travelling parallel to the center line, meets the center line (principal axis).
