I don't know where to put this one. The resolving power of a microscope(simple) is defined on the basis of diffraction effects.I have read that and as far as my understanding goes it is 2μsinβ/(1.22λ). This was assuming circular aperture for the lens.
[Here 2β is the angle subtended by the diameter of the lens at the object which is approximately at the focus]
However in some texts I have found the 1.22 factor missing. Isn't the factor a consequence of the circular aperture of the lens? I don't know much as I am not familiar with the kind of math used to calculate it. Can someone resolve this contradiction? Which is the more appropriate expression?
