|(functioning as singular) physics the formulation of quantum mechanics in which the behaviour of systems, such as atoms, is described in terms of their wave functions|
|an extraordinary or unusual thing, person, or event; an exceptional example or instance.|
|a gadget; dingus; thingumbob.|
A theory that interprets the behavior of matter (especially subatomic or other small particles) in terms of the properties of waves. A broad range of physical phenomena, from the propagation of earthquakes to the structures of electron orbitals in atoms, have been understood using wave mechanics. Quantum mechanics uses a form of wave mechanics and involves wave equations such as Schrödinger's equation to capture both the wavelike and particlelike properties of matter.
