The term diffraction is applied to problems in which one is concerned with the resultant effect produced by a limited portion of a wave surface. If only a part of the wave is cut off by some obstacle, are the effects commonly called diffraction. Diffraction is sometimes defined as the bending of light around the obstacle and its presence in the region of geometrical shadow.
