A particle of electromagnetic radiation with no mass that carries a quantum of energy?
Bear in mind that anything that has energy also necessarily has some amount of mass, however small, in accordance with the famous equation e = mc2. Photons are said to have no rest mass, but since they are never at rest that is a purely theoretical characteristic. Photons have no mass other than the small amount to which their energy content is equivalent.
Explain how photoelectric effect confirms particle nature of radation?
The photoelectric effect is a quantum electronic phenomenon in which electrons are emitted from matter after the absorption of energy from electromagnetic radiation such as x-rays or visible light.
What do you call a particle of light with zero mass which carries a quantum of energy?
I call it a 'photon'.By the way, the photon has zero rest mass, but when it travels at the speed of light ...which it always does ... it has some mass.
Which particle is most involved with quantum theory?
The photon - definitely.
What type of radiation do black holes produce?
The recent work by Professor Hawking wherein he described a thermodynamic interaction with the universe originating in quantum effects near the event horizon takes his name, "Hawking radiation". The nature of the radiation itself is described as a particle-antiparticle pair (produced by intense gravity from the black hole acting upon a virtual particle) or sometimes as a quantum tunneling effect from just inside the event horizon; the negative component of which gets "added" to the black hole and thus reduces its mass (radiates inward) while its counterpart radiates outward. It is also calculated to be a very weak form of radiation.
What is a particle of electromagnetic radiation with no mass that carries a quantum of energy?
Photon
A unit or quantum of light a particle of electromagnetic radiation that has zero rest mass and carries a quantum of energy?
Photon
What is the electromagnetic force transmitted by?
Electromagnetic force is transmitted by photons. Photons are a particle representing a quantum of light or other electromagnetic radiation. It carries energy proportional to the radiation frequency but has zero rest mass.Ê
Gravitational radiation is composed of streams of photons or elemtary particles of electromagnetic waves?
No. Gravitation is not electromagnetic radiation, and no quantum (elementary particle) of gravitation has been found yet. If the speed of propagation of gravitation is not infinite, that hasn't yet been measured either.
Where is the photon on the eye?
A photon is an elementary particle, the quantum of light and all other forms of electromagnetic radiation, and the force carrier for the electromagnetic force, even when static via virtual photons. The photon is not on the eye.
What does photon mean?
In Chemistry it is a particle of electromagnetic radiation wth no mass that carries a quantum of energy. HOPE THIS HELPS:>photon is another name for concentrated energy, usually in quantizaed units.A photon is a particle of light. For more details, read the Wikipedia article on "photon".meant*A photon is like a particle of light. The minimum divisible quantity of light.
Is light a radiation or a particle?
Yes, it acts like whichever your experiment is testing for. This is one thing about quantum mechanics that confuses many people (and probably cannot be fully understood by the human mind). Also, its not just electromagnetic radiation, but matter acts the same way (sometimes a wave sometimes a particle).
What happens When a photon strikes a solar cell?
When a photon strikes a solar cell it bounces off. In Physics, a photon is an elementary particle, the quantum of the electromagnetic interaction and the basic unit of light and all other forms of electromagnetic radiation.
What is a quantum of electromagnetic radiation usually considered as an elementary particle that is its own antiparticle and that has zero rest mass and charge and a spin of one?
You have described a photon. Fairly well, actually; good job.
What theory of light best explains the emission of electromagnetic radiation of an excited atom?
Quantum Mechanics
What is ionizing radiation and how can we reduce the risk of it damaging us?
Ionizing radiation is electromagnetic radiation or particulate radiation having enough energy per quantum to remove electrons from atoms, thus creating positive ions.The types of electromagnetic radiation with enough energy per photon (the quantum of electromagnetism) to ionize atoms are:ultraviolet Cx-raysgamma raysThe types of particulate radiation with enough energy per particle (i.e. quantum) to ionize atoms are:alpha particlesbeta particlescosmic rays (both primary and secondary)The only way to reduce the risk is to minimize exposure, but remember exposure cannot be completely eliminated as all of these types of ionizing radiation are present at low dose rates all around us.
Is light a gas or a mass?
If you stay outside the realms of quantum physics, then it is neither - it is a form of electromagnetic radiation.
