Define Rayleigh criterion or resolving power

Rayleigh criterion: resolving power: The criterion for determining how delicately a set of optics might be able to differentiate. This starts with the supposition that central ring of one image must fall on the first dark ring of the other; for an objective lens with diameter d and utilizing light with a wavelength lambda (generally taken to be 560 nm), the resolving power is about specified by:

1.22 lambda/d
