    Power of A Lens

    Q: What do you mean by power of a lens?
    A: The power of deviating of a ray of light by a lens is inversely proportional to the focal length of the lens.
    It is the power which is known as the power of lens. It is given by P=1/f. Its S.I. unit is diopter.
    It is a characteristic of lens which does not depend upon distance of object(u) and distance of image(v). It is the sum of the powers of its refracting surface.
