The theory basically says that energy is radiated in discrete, tiny packets called quanta.

She delivered her words like photon torpedoes, discrete packets of energy targeted at her quarry.

Often, a block in a data flow diagram has a single input and a single output, and operate on discrete packets of information.

He had isolated discrete packets of molecules within Seven where once, much cruder machines had been integrated into her organic systems.

Photon: a discrete packet of electromagnetic energy.

Due to the nature of this acceleration, the beam must be separated into discrete packets, or 'bunches'.

Perhaps, therefore, angular momentum was also quantised, also came only in discrete packets.

Photon energy is quantized (e.g. it only exists in discrete 'packets').

Einstein showed that, by assuming that light actually consisted of discrete packets, he could explain the mysterious photoelectric effect.

Prior to the 19th century, light was believed to consist of discrete packets called corpuscles.
