Explanation:
Using the Reyligh creterion for diffraction through a circular aperture we have
where symbol's have their usual meaning

The work-energy theorem states that the change in kinetic energy of the particle is equal to the work done on the particle:

The work done on the particle is the integral of the force on dx:

So, this corresponds to the change in kinetic energy of the particle.
