a photon
Photons
A particle of light. Or, in general, of an electromagnetic wave.
A photon is a particle of electromagnetic radiation with no mass that carries a quantum of energy. It is the fundamental unit of light and other forms of electromagnetic radiation.
Light is energy, and energy is not matter.
A photon is a fundamental particle of light that carries electromagnetic energy and behaves as both a particle and a wave. It has no mass and travels at the speed of light. Photons are the basic unit of all electromagnetic radiation, including visible light, radio waves, and X-rays.
Light quanta are discrete packets of energy known as photons that make up electromagnetic radiation, including visible light. These particles exhibit both wave-like and particle-like properties, and are the basic unit of light energy.
Radiant energy. Light is a form of electromagnetic radiation.
The particle of energy that makes up light is called a photon. Photons are massless, electrically neutral particles that carry electromagnetic radiation.
The particle that carries radiant energy is the photon. Photons are elementary particles that travel at the speed of light, carrying energy in the form of electromagnetic radiation. They are responsible for phenomena like light, heat, and other forms of radiant energy.
The common definition of 'light' (visible) is electromagnetic radiation visible to the human eye. It is only a small part of what is known as the 'electromagnetic spectrum' - which is the range of wavelengths of all possible electromagnetic radiation. Light is electromagnetic radiation, as reported. But, even though it behaves like a wave, it also behaves as a particle. We can call a particle of light a photon. Light has two identities, a "duality" of sorts, that is called wave-particle duality. That's about as simple as it can get. Light is called a "wavicle" by some, and for reason that it displays qualities of both a wave and a particle.
This is variously known as light energy, radiant energy, and electromagnetic radiation.
A photon is a fundamental particle of light that carries energy. It has no mass and travels at the speed of light. Photons play a crucial role in various phenomena like electromagnetic interactions and the photoelectric effect.
