I was told that for an electron, the wave length lamda calculated from De Broglie's equation ( = h/p ) refers to the wave length of its probability function (as solution to Schroedinger's wave equation ), and is not its physical wave length as exhibited in the electron's double slit diffraction nor diffraction through crystals.(adsbygoogle = window.adsbygoogle || []).push({});

At the same time, for photons we take lamda= h/p as the actual/physical wave length of the light.

Can someone shed some light on this apparent inconsistency?
