Hey guys, Ive been trying to find out an answer to this question I had today but couldn't find it. The question is regarding the measurement problem and the observer effect for the double slit experiment. Say I have 2 electron detectors labeled A and B respectively. Detector A is located at the slit openings to observe which slit a single electron goes through and detector B is located on the screen to observe where the electron hits. In this experiment, electrons are fired one by one. If I, the observer, only watches detector B and never observes detector A while detector A is on, does the wave interference collapse or will I see the wave pattern?
