Photons can be thought of as both waves and particles. So, the theory is, if the behavior of photons is described by a wave equation, it stands to reason that the behavior of other elementary particles can also be described by a wave equation.

Luis deBroglie (1892-1987) a French physicist - found that a wave function is associated not only with elementary particles, but with all particles. Where this wave function has an amplitude, there is likely to be a particle. He received the Nobel Prize for Physics in 1929 - for “his discovery of the wave nature of electrons".

The wave function for a particle is called a 'matter wave' - the intensity of the wave function of a particle at a given point is proportional to the probability of finding the particle at the same point. The relationship between momentum and wavelength for matter waves is given by the equation

p = h/λ,

where p = momentum, h = Planck's constant and λ = wavelength. At non-relativistic speeds, the momentum of a particle is equal to its rest mass m, multiplied by its velocity v or

p = mv.

The ‘Broglie wavelength’ λ — is h/p - in nanometers.
