The wave nature of the electron must be invoked to explain the behavior of electrons when they are confined to dimensions on the order of the size of an atom. This wave nature is used for the quantum mechanical particle in a box and the result of this calculation is used to describe the density of energy states for electrons in solids. Electron diffraction from crystals which confirm wave nature of electrons. Quantum mechanically, an electron can be described by a wave function oscillating in space and time that has mean values equal to the expectation values of observables corresponding to given operators. In the scope of a hundred pages, the author has discussed electron wave properties, the early history of the experimental side of the subject, diffraction by transmission and by reflection.

This video is about the electrons and the debroglie wave and the particles present in the nucleus. The electron is in fact given a complete outfit of eulerian angles, even if it may not be necessary so to express the matter explicitly. Electrons are found in certain orbits because they interfere with themselves and create. Now we regard the electron as the most primitive thing in nature, and it would therefore be much more satisfactory if the duality could be obtained without such great elaboration. The photoelectric effect pointed to the particle properties of light, which had been considered to be a wave phenomenon.
