Hi
I wonder if I could get help with some questions that have puzzled me related to the two split experiment and electromagnetic interference in general.
I know that if you shine a laser beam through the two split experiment then inference patterns will appear, and that if the path of a photon traveling through the experiment is measured or known then the interference patterns break down.
I have also read that this also works if two (identical) laser beams are combined, i.e interference occurs. If the laser beams were 180deg out of phase then the peaks and troughs would cancel out the beam.
1. Can I assume that, if I were able to determine which laser beam an individual photon came from the interference would also break down?
2. I was wondering whether this works exactly the same for radiowaves? If I were to position a receiving aerial between two radio transmitters, (some distance apart), that were transmitting the same frequency radio signal but 180deg out of phase the radio signal would be canceled out and the aerial should not receive anything.
3. If I now added two more receiving aerials, each one positioned slightly closer to one of the transmitters. By comparing the difference in signal and phase between the first aerial and the second new pair of aerials I should surely should be able to work out the path of the radiowaves. Does the interference breakdown? Do I suddenly receive a signal from all the aerials or just the second pair or maybe nothing changes?
4. If this is true what happens if the two transmitters are now brought close together (I guess near field). Do the same effects happen?
I may be well off track so please forgive my lack of knowledge. I may have to go and buy some radio equipment...
Thanks
Steve
