Option 3 : Davison and Germer experiment
The correct answer is Davison and Germer experiment.
- The Davisson and Germer experiment demonstrated the wave nature of the electrons, confirming the earlier hypothesis of de Broglie.
- Electrons exhibit diffraction when they are scattered from crystals whose atoms are spaced appropriately.
- Putting wave-particle duality on a firm experimental footing, represented a major step forward in the development of quantum mechanics.
- Davisson and Germer designed and built a vacuum apparatus for the purpose of measuring the energies of electrons scattered from a metal surface.
- Electrons from a heated filament were accelerated by a voltage and allowed to strike the surface of nickel metal.
Apparatus of Davisson and Germer experiment
| Experiment | Description |
| Photoelectric effect | The photoelectric effect is often defined as the ejection of electrons from a metal plate when light falls on it. |
| Double slit experiment | It suggests that what we call "particles", such as electrons, somehow combine characteristics of particles and characteristics of waves. |
| Compton effect | The Compton effect (also called Compton scattering) is the result of a high-energy photon colliding with a target, which releases loosely bound electrons from the outer shell of the atom or molecule. |
