RELATION BETWEEN POWER OF LENS AND FOCAL LENGTH

Answer»

Optical power (ALSO REFERRED to as DIOPTRIC power, REFRACTIVE power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges LIGHT. It is equal to the reciprocal of the focal length of the device: P = 1/f.
