Detailed explanation-1: -The fundamental particle of light is both ordinary and full of surprises. What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible packets of electromagnetic energy.
Detailed explanation-2: -A substantial energy value and momentum strongly indicated that the light quantum could be associated with a particle. This particle was later named photon. Therefore, a photon is defined as a discrete bundle (or quantum) of electromagnetic (or light) energy.
Detailed explanation-3: -Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object’s atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.
