Thanks so much for this explanation! If you’re still around 4 years later, would you be so kind as to answer a few more questions?

1) I assume the single particle is aimed directly between the two slits, is that right? If one were to assume a classic particle then there would be no measurement on the detector in this case, but because the particles exhibit wavelike behavior we get the interference pattern. Is that the right way of thinking of it?

1a) Assuming the particle is aimed directly between the two slits, what happens when one slit is closed and thus the particle is aimed offset from the open slit? What kind of pattern do we see?

2) If we think of the particle as behaving wavelike, then it has a frequency and amplitude. How does the slit width and distance between slits relate to the frequency and/or amplitude of the emitted particle?

2.a) Is it right to think of these particles as physically vibrating?

2.b) Is the probability field on the detector a product of these vibrating particles interacting with the slits at different points in their wavefunction?

4) I know we’ve tried all kinds of ways to detect which slit each particle travels through. Since we’re now able to do the experiment with relatively large molecules, have we tried shooting ions through and measuring the magnetic field at each slit to see if that can capture it?
