What is a discrete bundle (or quantum) of electromagnetic energy called?

Explanation:
A photon is a single quantum of electromagnetic energy. In quantum theory, light energy comes in discrete packets, and that specific packet is called a photon. Each photon carries energy proportional to its frequency (E = hν) and momentum related to its energy. So while light can behave like a wave and energy exchange with matter occurs in these discrete units, the precise name for one of those energy packets is photon. The term quanta describes the general idea of these discrete units, but the standard name for the actual packet of EM energy is photon.
