I just saw a video about the so called "Double Slit Experiment" () which showed that two lightbeams that are parrallel will manipulate each other just like waves in a pond would do.
The slits used in this experiment were very close together but you could see them with your eye so I guess they were a millimeter or the tentht of a millimeter apart.
My question is: How big is the amplitude of light meaning the distance from the negative to the positive peak in millimeter (or any other unit of length). If the two beams in the video could interact with each other my conclusion would be that it must be at least half the distance of the two slits but if that's the case then why do glass fibre cables work? They should be much to small to allow such a big amplitude.
PS: I'm not a native speaker so I hope I didn't make to many mistakes ;)
