Can travel with a velocity greater than the velocity of light. 2Wavelength depends on the mass of the particle and its velocity λ=h/mט 3. Matter waves 1.Matter wave is associated with moving particle. 5ĭifference between matter wave and E.M.wave:: O o Thus the wave nature of matter introduces an D a uncertainty in the location of the position of the a Heisenberg’s uncertainty principle is Fparticle. While position of a particle is confined to a g n particular location at any time, the matter wave E associated with it has some spread as it is a wave. This reveals that these waves are not electromagnetic but a new kind of 4 waves.Ħ.No single phenomena exhibits both particle nature and wave nature simultaneously. Whether the particle is charged or not, matter wave is associated with it. This means that only with moving particle matter wave is associated. Lesser the velocity of the particle, longer the wavelength associated with it. Lighter the particle, greater is the wavelength associated with it. The wave associated with matter called matter wave has the wavelength λ=h/mט and is called de Broglie wavelengthĬharacteristics of matter waves Lecture-3 According to Louis de Broglie since radiation such as light exhibits dual nature both wave and particle, the matter must also posses dual nature. According to Plank’s law, the energy of photons per unit volume in black body radiation is given by Eλ=8πһс∕λ5 According to Plank’s quantum theory, energy is emitted in the form of packets or quanta called Photons.Ģ.
