Explanation:
☑️ 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 traveling parallel to the center line, meets the center line (principal axis). The radius of curvature (r) is the radius of the lens that forms a complete sphere.
