Frequency or wavelength of a photon

[Schrodinger's Dog]

Thanks very much for your explanation and time. One last question based on the above statement (maybe). Suppose a situation where there were "two photons" (eg, simultaneously at both sites) and not "just one"--do you know of any experimental design at could detect "two photons simultaneouly" at the slits--can you provide a reference ?

Your welcome, I had the same questions as you going into learning about it, luckilly though I found a discussion on here and then followed some links and found a few of my own. I saw the others description and I figured they may be using concepts you weren't familliar with so I tried to put it in very simple language, a sort of idiots guide, the same sort of information I had when I was learning about it, without getting to heavilly involved in maths or relatively obsucre terms too early on. Now go and learn about special relativity, that's a bit of a mind melt at first too
