Aim of the experiment
To prove the existence of matter wave associated with a moving particle.
3
Idea behind the experiment
4
In x-diffraction by crystal, x-ray beam is strongly reflected when the beam strikes the the crystal at an angle that gives constructive interference among the waves diffracted from parallel planes.
Idea behind the experiment
Condition for getting diffraction maxima 2dsinθ=nλ
If a wave is associated with moving electron then elctron beam will show x-ray like diffraction maxima
