In physics, a quantum (pl.: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. Quantum is a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents.
Oct 17, 2024 · Quantum, in physics, discrete natural unit, or packet, of energy, charge, angular momentum, or other physical property. Light, for example, appearing in some respects as a continuous electromagnetic wave, on the submicroscopic level is emitted and absorbed in discrete amounts, or quanta.
Apr 11, 2024 · Quantum, often called quantum mechanics, deals with the granular and fuzzy nature of the universe and the physical behavior of its smallest particles.
quantum. (ˈkwɒntəm) n, pl -ta (-tə) 1. (Atomic Physics) physics. a. the smallest quantity of some physical property, such as energy, that a system can possess according to the quantum theory. b. a particle with such a unit of energy. 2. amount or quantity, esp a specific amount.
(kwɒntəm ) 1. adjective [ADJECTIVE noun] In physics, quantum theory and quantum mechanics are concerned with the behaviour of atomic particles. Both quantum mechanics and chaos theory suggest a world constantly in flux. 2. adjective [ADJECTIVE noun]
While quantum refers to a general quantity or size, it is most often used in physics as a measure of the smallest amount of something — usually energy — that something can possess. The plural form is quanta.
