Quantum is the minimum amount of any physical entity or property involved in an interaction. Learn about the discovery of quantization by Planck and Einstein, and the implications of quantum mechanics for matter, radiation and energy.
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.
