I think what you need to know is the reason the most extreme bright spot is the focal belt and from it starts to diminish in force? the appropriate response is: on account of the way the contrast between the middle point and the break and alternate parts of the screen have a more noteworthy separation.
In single silt diffraction, accepting little diffraction points, the force profile is the greatness squared of the Fourier change of the capacity which is steady between - 1 and 1 (up to units of length), and this Fourier change is sin(x)/x.
This has a crest at zero, as a result of the falloff of 1/x yet in particular, and this can be seen subjectively, the initial zero of sin(x) is missing, the focal most extreme is twice as wide as all the others.
