Davisson and Germer Experiement
Davisson and Germer experiment involved the following steps:
- A beam of electrons was produced and directed at a crystalline nickel target.
- The atoms of the nickel crystal scattered the electrons, and the angular dependence of the scattered electron intensity was measured.
- The electron beam was moved on a circular scale, and the intensity of the scattered electrons was measured at different angles.
- By changing the accelerating potential difference, the accelerated voltage was varied from 44V to 68V
The observations made during the experiment showed that the electrons exhibited wave-like behavior, as the nickel crystal scattered them in a manner similar to the diffraction of light by crystals. The experiment confirmed the de Broglie hypothesis. This finding and the Compton effect discovered by Arthur Compton established the wave-particle duality hypothesis, which was a fundamental step in the development of quantum theory.
Dual Nature of Matter
Dual Nature of Matter states that a matter exhibits both Particle Nature and Wave Nature. It means that when a matter is at rest it behaves like a particle and when it is moving it behaves like wave. Different Experiments have been performed to prove this by the science community.
In this article, we will look into this theory and understand the dual nature of matter. We will also learn the experiments that proved the dual nature of matter.
