Question

Write the lens formula in terms of power​

Answer 1

1/v- 1/u= 1/f

1/v- 1/u= P[ since P= 1/f]

Answer 2

The diopter is the unit of measure for the refractive power of a lens. The power of a lens is defined as the reciprocal of its focal length in meters, or D = 1/f, where D is the power in diopters and f is the focal length in meters. Lens surface power can be found with the index of refraction and radius of curvature.
