How power of lens is affected by its curvature?

Expert Answer
The answer to this question is similar to the previous one wherein dependence of power on focal length is explained. The power of a lens is the degree to which a lens converges or diverges the light incident on it. Now, this convergence or divergence will depend on how much the lens is curved.
A lens which is higly curved means that it will have high convergence or divergence to offer to the incident light. Similarly, a lens which is slightly curved means that it will have less convergence or divergence to offer to the light. In this way, power of a lens is dependent on the curvature of the lens.
