Okay so we have a series of electrons going through the famous 2 slits and the wave-nature of the electron causes an interference pattern to emerge on the back plate.
So far so good. But now we put a detector behind slit-A and the interference pattern goes away. Now I have 2 questions.
1) If we put the detector behind slit-B, does a different pattern emerge on the back plate? How is it different?
2) IF the pattern goes away simply because the photon from the detector is interfering with the wave aspect, then that seems reasonable. But then why all the fuss about "Observation" and the possibility that a "human-witness needs to be involved to collapse the wave-function" etc. IS this all just a big Misconception?
Thanks in advance.
