A particle of light energy is called a photon. Photons are the fundamental particles of light and are responsible for electromagnetic radiation. They are unique in that they have no mass and travel at the speed of light in a vacuum. Photons can carry energy in discrete amounts referred to as quanta, which is a key principle in quantum mechanics. This is why they are considered particles of light energy, as they facilitate the transfer of energy from one point to another, such as in the case of sunlight warming the Earth or light illuminating a room.

In contrast, positrons are the antimatter counterparts of electrons, neutrons are subatomic particles found in the nucleus of an atom, and a betatron is a type of particle accelerator used to produce high-energy electrons. These terms refer to different concepts within physics and do not relate to the properties or characteristics of light energy specifically.
