According to our science textbook focal length(f) of a mirror/ lens is equal to half its radius of curvature(R).Which means that there is a specific focal length for a given lens/mirror(f=R/2). The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. A system with a shorter focal length bends the rays more sharply, bringing them to a focus in a shorter dista…
