If we perform the two slit experiment vertically - so the slots are above one another - we should observe a small amount of red / blue shift in the energy of the photons when they hit the screen (due to gravity). The path length from each slit is not symetric so the arriving photons energy would...

Interesting - thanks. But surely if the lasers light was of incoherent phase each photon would display the interference pattern (but being a individual we would only see it in one location) - other photons would be out of phase so we might expect after many photons a strip of light with no...

Actually - after a little more thought - why bother moving the waves over time? If your interested in the coherence of the waves we could much more easily image the waves as standing wave with its propagation over time...perhaps that's a side question!

Yeap - definitely was! I think i now see now why the sum of the amplitudes can be taken from the centre wave because your interested in the directionality of the two vectors. But... I think the second part of my first question still stands...(or at least you can correct me on this too!) If...

So that typical diagram of waves going through the slots is not entirely correct? It is only correct for that one screen position? (The one where arcs representing wave peaks radiate from each hole and the amount of interference on the screen is given by the two creasts overlapping). On...

In a standard 2 slit experiment setup when the interference pattern is visible - if the screen is moved forward the pattern must 'move' across the screen as the alignment of wave peaks and troughs change. I.e if we start with an intense band at the centre then move the screen forward half the...

Of course. Although I am thinking about all em waves...

Particles emit and absorb light of certain quanta and various factors can then red or blue shift this energy. Does this mean light sometimes gets shifted into a frequency which is unable to be absorbed by any particle and therefore can longer be 'seen'? (At least until it is shifted further...)

Sticking with hydrogen example - you are saying if we make it an anion (and change the pe).. this makes the orbital more voluminous?

So let's say we have a hydrogen 1s1 cloud - you are saying it has a different the size volume cloud as its anion hydride 1s2? What if we add a neutron - is the volume still the same? (i would have guessed that its opposing spin electron would be permitted permitted in the same volume?)

Do electrons all orbit an nucleus at the same distance? I.e is an 's' cloud always the same in every atom or does the chance of finding one closer or further to the nucleus change? What about when the spin opposite electron enters the shell?

can we extend this question a little further (yes I did read your link).. What are some examples of photons acting like waves? The dbl slit seams like an obvious answer but if we look one particle at a time it never is a wave - it doesn't hit the screen in parts - just quanta. Why don't we...

If You have a Cartesian co-ord system of x, y, z with origin set at 0,0,0 then you need to add or subtract from the x, y, z of the function by the amount you are moving the origin. Ie if y=3x at origin x0,y0 then at a new origin x4,y3 the function will be y+3=3x+4 or y=3x+1.

Hi, is there a median number between zero and one? There are countless numbers between zero and one - an infinite set. If we pick any number at random (say 0.2) then could we always say it is the median as there is an infinite set of numbers on either side? What if I pick another...

Agreed. But the interference patterns which manifest in locality is maths - a vector space designed to construct and assertian the photons properties but its not actual space in the real world - so I don't see a problem in visualising a photon as point as that is how is shows up (albeit...
