WebMar 1, 2024 · If you look at diagrams of Fraunhofer single-slit diffraction patterns, you will see that the central maximum is symmetrical about the center line. All the other maxima and minima are found on just one side of the center line. Of course, the pattern as a whole is also symmetrical about the center line. A grating is defined in Born and Wolf as "any arrangement which imposes on an incident wave a periodic variation of amplitude or phase, or both". A simple grating consists of a screen with N slits whose width is significantly less than the wavelength of the incident light with slit separation of S. The complex amplitude of the diffracted wave at an angle θ is given by: joey greenwald attorney shreveport la
