## Matter waves (de-broglie waves), Physics

Assignment Help:

It is described by de-Broglie a moving material molecule sometimes acts as a wave and sometimes as a particle.

The wave associated with moving particle is known as matter wave or de-Broglie wave and it propagates in the form of wave packets with group velocity.
