Describe Davison -Germav Experiment ?by drawing its setup and wave form?These experiment explain the wave nature of e⊝
By using an electron gun heated by a low power
supply, electron beams were emitted at the desired velocity by applying
suitable potential difference from a high voltage power supply. These electrons
were made to pass through a cylinder with fine holes thus forming a finely
collimated beam. Then this collimated beam was made to fall on the surface of a
nickel target which led to the scattering of electrons in various directions.
The nickel target was rotated to observe the scattered electron. The detector
was mounted on an arc to observe electrons at different angles which could be
rotated in a circular movement. It was noted that the deflected electrons
pattern was similar to the diffraction of waves. Also, it was noted that at
certain angles the intensity of scattered electrons was high at a voltage of 54V and at a scattering angle of 50o.
