The Quantum Theory of Waves and Particles - University of …
WEBFree, propagating particles in quantum theory are represented by an intermediate case, a wave packet: We arrive at a wave packet by adding matter waves with a small range of momenta. The resulting packet occupies a range of positions in space and is associated with a range of momenta.
Wave–particle duality - Wikipedia
WEBWave-particle duality is the concept in quantum mechanics that quantum entities exhibit particle or wave properties according to the experimental circumstances. [ 1 ] : 59 It expresses the inability of the classical concepts such as particle or wave to fully describe the behavior of quantum objects. [ 2 ] :
Quantum mechanics - Wikipedia
WEBQuantum mechanics allows the calculation of properties and behaviour of physical systems. It is typically applied to microscopic systems: molecules, atoms and sub-atomic particles.
WEBIn quantum mechanics, particles have wavelike properties, and a particular wave equa-tion, the Schrodinger equation, governs how these waves behave. The Schrodinger equation is di®erent in a few ways from the other wave equations we've seen in this book.

Science Made Simple: What Is Quantum Mechanics? - SciTechDaily
WEBNov 19, 2023 · Quantum mechanics is the field of physics that explains how extremely small objects simultaneously have the characteristics of both particles (tiny pieces of matter) and waves (a disturbance or variation that transfers energy). Physicists call this the “wave-particle duality.”.
6.7: Wave-Particle Duality - Physics LibreTexts
WEBSep 12, 2022 · Quantum mechanics takes de Broglie’s idea of matter waves to be the fundamental property of all particles and gives it a statistical interpretation. According to this interpretation, a wave that is associated with a particle carries information about the probable positions of the particle and about its other properties.
