Diffraction of a Plane N Wave of Finite Amplitude by a Slit.
Abstract
A theoretical and experimental study of the diffraction of a plane N wave of finite amplitude by a slit is presented. The N waves used in the experiment were produced by an electric spark, which was located at the focus of a parabolic dish. The plane wave was normally incident on a 2.38 cm wide slit in a rigid baffle. Peak pressures at the slit of 99 mbar, 47 mbar, and 29 mbar were used. The corresponding time durations were 74, 34, and 25 microseconds. The spatial and temporal properties were obained from schlieren and microphone measurements, respectively. A linear theory for slit diffraction was found from a time domain version of the Green's function solution.
