I'm feeling good because I have confirmed my belief that photons passing through a hole (or so-called "slit") in for example, a metal sheet, do spread out, apparently not because of an interference pattern, but because of the number of times they reflect off the inside sides of the hole. The so-called "orders", I think, this video clearly shows, can just as easily be interpreted as the number of times a beam of light has been reflected. Photons reflect off the inside of a slit and cause what many thought is an interference pattern, but what may be more accurately explained as a reflection pattern. Order n=0 is no reflection, n=1 is reflected one time, n=2 is reflected two times, etc.
