As the number of sides of the polygon increases (N approaches infinity), the aperture behaves more like a circular aperture. The task is to calculate the angular separation between the first two intensity minima in the resulting diffraction pattern. The solution leads to the conclusion that the angular separation is given by 0.506 \u03bb / a, where \u03bb is the wavelength of the light and a is the length of the apothem."}
