It is determined that the difference of the light amplitudes in the bands of the diffraction pattern due to the screen and the corresponding amplitudes of the incident wave is inverse proportional to the distance from the shadow boundary.
Simple expressions are derived for the intensity of the edge wave and and the intensity of the diffraction pattern, and are in good agreement with the experimental data.
