What is dual nature of matter? Dual nature of matter - Since radiation has dual nature i.e. it possess properties of both; wave and particles and universe is composed of radiation and matter, therefore de-Broglie concluded that the matter must also possess dual nature, since nature loves symmetry. Dual nature of matter De-Broglie hypothesis about dual nature of matter De-Broglie hypothesis about dual nature of matter 1) According to De-Broglie, a moving material particle sometimes acts as a wave at some times as a particle or wave is associated with moving material particle which controls the particle in every respect. The wave associated with moving material particle is called matter wave or de-Broglie wave, whose wavelength is given by, λ = h/mv where m is the mass of the particle moving with velocity v and h is Planck's constant. 2) De-Broglie wavelength associated with electron accelerated under a potential difference V volt is given by λ = 12.2...
