Answer:
The velocity of the matter-wave is not constant since it depends upon the velocity of the material particle.
Matter-wave
A matter wave is a wave associated with each moving particle. The wavelength of a matter wave is equal to
λ = hp
where
- h = Planck’s constant
- p = The moving particle’s moment
Characteristics of matter-wave
- Matter waves are not electromagnetic in nature
- Matter-wave represents the probability of finding a particle in space.
- Matter waves are independent of the charge of the material particle.
- Electron microscope works based on de-Broglie waves.
- Matter waves can propagate in a vacuum. Hence they are not mechanical wave.
- The number of de-Broglie waves associated with the nth orbital is n.
- The phase velocity of matter waves can be greater than the speed of light.
