The quantum of light and other electromagnetic energy, regarded as a discrete particle having zero rest mass, no electric charge, and an indefinitely long lifetime. It is a gauge boson
a quantum of electromagnetic radiation; an elementary particle that is its own antiparticle

A packet of electromagnetic energy Photons have momentum and energy, but no rest mass or electrical charge
The quantum of electromagnetic energy at a given frequency This energy, E=hv, is the product of the Planck constant (h) and the frequency of the radiation (v) Related term: quantum [IUPAC Photo]
A discrete quantity of electromagnetic energy Short wavelength (high frequency) photons carry more energy than long wavelength (low frequency) photons See Electromagnetic Radiation
