Question

tell me lens formula???​

Answer 1

Answer:

hii buddy

Explanation:

The diopter is the unit of measure for the refractive power of a lens. Thepower 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

hope it helps.....
