Hi friend,

MATTER WAVES:-

The waves associated with the moving particles proposed be the de- Broglie is known as matter waves.

DAVISSION AND GERMER EXPERIMENT:-

The main principle of this experiment is to prove that the x-rays showing wave character.

Davidson and germer experiment in 1927 conformed the De-broglie wavelength of duality . It also confirmed the see Broglie's wavelength equation.

A beam of electrons obtained from a heated tungsten filament is accelerated through a high potential. It hits a nickel crystal and the electrons are scattered in different directions. The diffraction pattern obtained is similar to Bragg's experiment on diffraction of X-rays.

It is deduced that electrons too have wave nature as the X& rays have wave character. Only waves undergoes diffraction and pattern doesn't undergoes diffraction. The wavelength of the waves are nearly equal to the de-Broglie wavelength.

Apart from that G.P Thomson performed a experiment to verify the wave nature of the x-rays excepting the fact that the thin foil of Gold plate is used instead of nickel crystal.

Hope this helped you a little!!!
