Einstein had suggested that light could behave as a wave as well as like a particle i. e. it has dual character. In 1924, de-Broglie proposed that an electron, behaves both as a material particle and as a wave. This proposed a new theory wave mechanical theory of matter. According to this theory, the electrons, protons and even atom when in motion possess wave properties. According to de-Broglie, the wavelength associated with a particle of mass m, moving with velocity v is given by the relation, λ = h/mv where h is Planck’s constant.
