What are matter waves? Derive an expression for the de Broglie wave length.

Explanation

The wave associated with material particles in inotion are called inatter waves or de-Broglie waves.
de – Broglie wave length of a particie is given by
`lamda = (h)/(P) =(h)/(mv)`
Where h`to` plank.s constant.
m `to` mass of the particle
v` to` velocity of the particle.
