    • Abstract


      In this paper, the Fresnel diffraction patterns exhibited by apertures and obstacles having the shapes of the semicircle and the segments of a circle are described and explained in terms of the general theory proposed in the first paper of these series. The transition for a semi-circular aperture from the Fresnel to the Fraunhofer class of phenomena as the size of the aperture is diminished is also illustrated.
