quantum

- For a given physical phenomenon, such as electromagnetic radiation, the smallest quantity, such as that of
__energy__, that can exist independently. For such__phenomena__, any quantity above this can only exist in multiples of this unit. In the case of light, for, instance, energy can be absorbed or radiated only in multiples of these__discrete__packages called photons. - A quantum (1) utilized as a unit. For example, the quantum of
__electromagnetic__radiation is the photon, which is also called light quantum. - Any given quantity which can be counted or measured.
- symbol Q
- synonym quantized value
- One of the finite values derived from a quantity or phenomenon with an infinitely
__variable__range of values, through the__process__of__quantization__(1). Also called__quantum__(2).
