Question

What are de-Broglie waves? Establish the de-Broglie wavelength equation.

Answer 1

De-Broglie waves: The waves which are associated with matter are called matter waves or de-Broglie waves.
Wave equation, $\lambda =\frac{h}{mv}$
where, $\lambda$ - wave length, $h$ - plank's constant, $m$ - mass, $v$- velocity of wave.
