In a double slit experiment with electrons i have read that if you put a detector at one of the slits, the interference pattern disppears. What if i put on both the slits? I would think it will still disappear. Everywhere I have seen detector been put only at one of the slits and was wondering if there is some hidden meaning.
I may want to see if it is pasing thorugh both at the same time. In that case I may want to put detector at both the slits even though I have only 2 slits. what happens then?
