Then in 1923, D-Broglie made his suggestion and proved that when microscopic particles like electrons, protons, molecules, atoms are in motion, then they have a wavelength associated with momentum. That is, their nature becomes like a wave.

Hence, according to de Broglie, every substance has the properties of the wave, such as frequency, wavelength, wave amplitude, etc., and all properties of particles.
Wave mechanics or quantum physics
The branch of science under which the nature of matter is studied as both wave and particle. It is called wave mechanics or quantum mechanics.
In the late 19th century and early twentieth century, some experimental facts were found in which interactions of radiation with matter take place. All such facts could not be interpreted by Chirasamat Machinery. In order to successfully explain all these phenomena, a new theory has been formulated which is called the Quantum theory.
Some such practical and theoretical facts are given below. Those could not be explained by classical mechanics, but they could be explained by quantum theory.
- Photoelectric effect
- Black body radiation
- Compton effect
