Particles or Waves: Why Do Electrons Exhibit Interference?

[gaugeboson]

If we use a normal gun sending out one bullet at a time, there is obviously no interference. However there is interference in waves. Still, if we send out electrons one at a time, they interfere with each other’s motion. Why is it so? Aren’t electrons particles?

 

[Kruger]

The wave function of an electron is a quantity to say something about the probability of finding the electron in space. Bohr's probability interpretation "connect's" the wave nature with the particle nature of quantas.

Firing bullets

The reason electrons interfere while bullets do not is because bullets are very very large and hence have very small wavelengths, so the probability distribution of the interference pattern is seen as essentially gaussian. Refer to Feynamn Volume 3, Chapter on double slit experiment (chapters 1,2 or 3 i believe).

 

[Antiphon]

Bullets do interfere. To see them interfere in a two-slit experiment, you would
have to launch them with a low enough momentum so that the wavlength was comparable
to the slit width.

And looking at a sufficient distance apart from the slits.
