Wave-Particle Duality

Dual Particle of wave

Another milestone to the wave particles arise in year 1924 when French Scientist called Loius de Broglie a stream of electron particles may have the same way particles like that of light, predict that a particle such electron particles  moving at a velocity v have a wavelength λ  which is given

 

Λ = h/mv

 

H = Planck’s constant

M = mass of the particles

In year 1927, C.J. Davison and L.H Germer an American scientist take a measurement of an electron beam by diffraction via crystal in such way that is similar to the diffraction of X rays. As such that confirmed de Brodlies hypothesis.

Point to know is that hypothesis of de Broglies has no limit. that is, his propose relationship is a general one. In every particle has it associated wave. The wavelength of the particle depend on the mass and the speed of it movement.

A particular location are occupied by particle, but there no exact position assign to wave. Extension of wave over a space region take place. As result of the wave properties, electron often spreads out, instead of been localized in a particular location. As result of this spread out of this electron. It make it impossible to determine the exact position of an electron. In another way the spread out of the electron is the root behind delocalization of electron and conduction of electricity, rather been pinpointed which cannot support conduction of current.

Watching electron and other particles-wave as delocalized, anyway modified the way we see things. Instead of things to poses actual position and location, the reverse is case, as being spread out of some volume. The beam of electron are deflected by magnetic field; this testify that electrons have a particle-like nature. Diffraction of electron is sign of the wave nature of electron.
