Question

what is meant by power of lens the reciprocal of. focal length is called power of lens or the divergence of convergence of light rays achieved by lens is called Power of lens​

Answer 1

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.

Answer 2

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.
