I get that the waves influence each other but I don't get my mind around why. If the two beams go straight through the slits their amplitue (y) has to be somewhere in the dimension of the distance between the slits (x) so that an "impact" or distorcion could take place.
Or is it like I tried...
Ahh okay so the slits have to be narrow enough to get effected by Heisenbergs uncertenty principle for this to work? And if so why does it form a pattern? To my understanding the spreading caused by the uncertenty should be absolutly random.
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...
