Phonon wave particle duality
Did you know?
WebThe concept of wave-particle duality says that light has properties of both a particle and a wave. It also says that small particles such as electrons behave like both waves and particles. This idea was proposed by Louis de Broglie when he outlined the results of some experiments in his PhD thesis. D e Broglie’s ideas are similar to Albert ... WebThis chemistry video provides a basic introduction into the concept of wave-particle duality. This includes the idea that photons and electrons can act as w...
WebSep 20, 2024 · Planck's investigation of the emission spectra of hot objects and the subsequent studies into the photoelectric effect had proven that light was capable of behaving both as a wave and as a particle. It seemed reasonable to wonder if electrons could also have a dual wave-particle nature. WebJul 21, 2010 · Mechanical waves also exhibit wave-particle duality. A "particle" is just a highly localized state. In the case of waves on water, it would be a drop, just hitting the surface. In the case of sound waves, it would be a small region of air with high pressure (the very moment of detonation, for instance).
The direction of the wave vector is the direction of the wave propagation and the phonon polarization vector gives the direction in which the atoms vibrate. Actually, in general, the wave velocity in a crystal is different for different directions of k. In other words, most crystals are anisotropic for phonon proagation. See more In physics, a phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids. A type of quasiparticle, a phonon is an excited state in … See more A phonon is the quantum mechanical description of an elementary vibrational motion in which a lattice of atoms or molecules uniformly oscillates at a single frequency. … See more Solids with more than one atom in the smallest unit cell exhibit two types of phonons: acoustic phonons and optical phonons. See more The thermodynamic properties of a solid are directly related to its phonon structure. The entire set of all possible phonons that are described by the phonon dispersion relations combine in … See more The equations in this section do not use axioms of quantum mechanics but instead use relations for which there exists a direct correspondence in classical mechanics.
