What is photon and how does photon relate to the electromagnetic radiation?
A photon is a fundamental particle representing a quantum of light or other electromagnetic radiation. It is a discrete bundle of energy that behaves like a particle and a wave simultaneously.
Photons are the carriers of electromagnetic radiation, which includes visible light, radio waves, X-rays, and gamma rays. These photons travel through space in the form of electromagnetic waves, carrying energy and information. The energy of a photon is directly proportional to its frequency, meaning that higher frequency photons have higher energy.
In essence, photons are the building blocks of electromagnetic radiation, and the interactions between photons and matter play a crucial role in many physical phenomena, such as the photoelectric effect and the emission of light by excited atoms.
