What is the wave particle duality of electrons?
All particles of matter, including electrons, exhibit characteristics of waves. The most obvious of these is the ability of particles to interfere with each other with a characteristic wavelength given by the de Broglie relation
If electrons initially at rest are accelerated through a potential of
Using the deBroglie relation, we can calculate the characteristic wavelength of the electrons as
If such a beam of electrons were diffracted from an ordered crystal, they would form a pattern similar to that for X-rays of the same wavelength (
