Abstract

Experimental evidence of the existence of the boundary diffraction wave is presented. The secondary wave occurring at the boundary of a sharp knife edge, interacts with each other while crosses the primary wave. This interaction and its path have been experimentally observed and recorded using a CCD sensor array. The observed diffraction profile of the composite wave has been discussed and briefly compared with the existing model of diffraction.
