Except that in the double-slit experiment we are observing the outcome of both cases in the exact same way.
In other words, our manner of interfering in order to observe the outcome of the experiment is no different in the case that results in the wave manifestation than in the case that results in the particle manifestation. In both cases, we are observing by measuring the impact of the electrons or photons on a screen after having passed through the slit or slits, in the same way.
So the different results cannot be explained by a difference in the way we are interfering in order to observe.
I didn’t follow that. Could you elaborate on how that applies for each case? Specifically, how do you apply the notion of observation deciding the outcome, and how do you keep the act of observation completely benign, in the double-slit experiment?
I’m also interested in knowing about the “neutrality” of the slits themselves, and how they ensure that only one particle is ejected at a time, with certainty.
What I’m basically trying to clarify, is the following. The particle-wave duality of electrons is confirmed by the double-slit experiment in the following manner:
Case 1: Pass electron beam through double slit, unobserved. Result: Interference patterns on screen.
Case 2: Pass electron beam through double slit, observed.
Result: No interference pattern on screen.
What I said earlier was that the act of observation was not benign.
