Development of Quantum Mechanics Waves
... If light is a wave with particle properties, are electrons particles with wave properties? C. J. Davisson and L. H. Germier at Bell labs proved that electrons produce diffraction patterns and verified deBroglies hypothesis ...

Synopsis
... Don’t try to work out the momentum of a high speed particle and hence its de-Broglie wavelength using its rest mass. Mas increase significantly as the speed of the particle approaches the speed of light! ...

Postulate 1
... something in common – wave properties. This led Schrodinger, in particular, to wonder whether equations used to describe light waves could be modified to describe the behaviour of electrons. This led to quantum mechanics and a probabilistic description of the behaviour of electrons. ...

Quantum Theory of Light. Matter Waves.
... Modern and Classical Physics Classical physics treats particles and waves as different aspects of the reality. However, the physical reality arises from small-scale world of atoms and molecules, electrons and nuclei. Electrons behave as particles because they have charge and mass, but moving electr ...
