Answer:
The Dual Behaviour of Matter...
Dual behavior of matter means that material particles at atomic scale in some circumstances behave as particles and in some circumstances behave as waves. ... The resulting wave is called a wave packet. Thus, wave packet can be used to describe a particle.
Einstein had suggested in 1905 that light has dual nature, that is, wave nature as well as particle nature. In 1923, Louis de-Broglie , the French physicist proposed that like light, matter also has dual character. It exhibits wave as well as particle nature. He even derived a relationship for the calculation of wavelength (A) of the wave associated with a particle of mass m, moving with velocity v as given below:
λ =h / mv or λ =h/p
where h is Planck’s constant and p is momentum of the particle.
The waves associated with material particles or objects in motion are called matter waves or de-Broglie waves. These waves are distinctively different from the electromagnetic waves.
The wave nature of electrons was experimentally verified by Davisson and Germer by electron diffraction experiment.
