One of the very small discrete packets into which many forms of energy are subdivided
The elementary quantity of EM energy that is transmitted by a particular wavelength According to the quantum theory, EM radiation is emitted, transmitted, and absorbed as numbers of quanta, the energy of each quantum being a simple function of the frequency of the radiation
(physics) the smallest discrete quantity of some physical property that a system can possess (according to quantum theory) a discrete amount of something that is analogous to the quantum in quantum theory
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
When used as a noun (plural quanta): a discrete quantity of energy, momentum or angular momentum, given in units involving Planck's constant h For example electromagnetic radiation of a given frequency f is composed of quanta (also called photons) with energy hf
