Question

What is a matter wave?

Answer 1

1. Matter-wave is an important part of quantum physics.
2. It is said that all matter shows wave-like behavior
3. The wavelength $\left(\lambda \right)$ of a matter-wave can be determined by is
   $\lambda =\frac{h}{p}$
   where $h$ represents Planck's constant, and $p$ represents the traveling particle's momentum.
4. The matter wave is also called as de Broglie wave.
5. The matter-wave describes the relationship between momentum and wavelength
6. The wavelength is inversely proportional to the momentum (mass and velocity) of the particle
7. The smaller the wavelength of the matter wave, the faster the particle moves.
8. The De-Broglie wavelength increases as the particle become lighter.
