Detailed explanation-1: -photon, also called light quantum, minute energy packet of electromagnetic radiation. The concept originated (1905) in Albert Einstein’s explanation of the photoelectric effect, in which he proposed the existence of discrete energy packets during the transmission of light.

Detailed explanation-2: -A packet of energy is called a photon. A photon is the smallest, discrete amount or quantum of electromagnetic radiation. It travels at the speed of light.

Detailed explanation-3: -A photon is a particle of light which essentially is a packet of electromagnetic radiation. The energy of the photon depends on its frequency (how fast the electric field and magnetic field wiggle, this needs better wording, for ‘fast electric field’ and ‘wiggle’).

Detailed explanation-4: -What Is a Photon? The light particle conceived by Einstein is called a photon. The main point of his light quantum theory is the idea that light’s energy is related to its oscillation frequency (known as frequency in the case of radio waves).
