Diffraction/Talk

How about a mention of single slit diffraction? --BlackGriffen Ok, how about some equations for it? Single slit and multi-slit diffraction don't obey the same equations. --BlackGriffen

I've added the equation for single slit diffraction. I think the two-slit case should probably be handled in the (currently non-existant) Youngs double-slit experiment article, since its under less general conditions (small slit widths = approximate point sources) and that's what people usually mean by double slit diffraction. -- DrBob
