As the number of sides of the polygon increases to infinity, the shape approximates a circular aperture. The task is to determine the angular distance between the first two minima in the diffraction pattern created by this aperture. Using the small angle approximation, the solution involves applying principles of diffraction to find the angular separation in terms of the wavelength and the apothem length."}
