Thanks, jtbell!
I still have some difficulty grasping the relationship between the De Broglie wavelength and actual physical systems and why the relation between wavelength and momentum is the way it is.
If I have a real particle and if I know its momentum (to some degree), I can determine...
The meaning of the De Broglie wavelength of a particle is entirely unclear to me.
1. To which kind of wave does the wavelength belong? To the wave that determines how likely the free particle is to show up in certain places (probabilities as squared amplitudes)?
If yes:
2. Why is the...
