What were Niels Bohrs contribution to atomic structure?
He understood the importance of quantum theory (and used it to explain the electromagnetic radiation produced when elements are excited when heated to high tempeatures or by being placed in discharge tubes).
Can a particle be diffracted?
Yes, a particle can be diffracted. Some of these are electrons and neutrons .This is a quantum mechanics theory stating that particles can exhibit wavelike properties.
What is the definition of electromagnetic wave?
Electromagnetic waves were first postulated by James Clerk Maxwell and subsequently confirmed by Heinrich Hertz. Maxwell derived a wave form of the electric and magnetic equations, revealing the wave-like nature of electric and magnetic fields, and their symmetry. Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave. According to Maxwell's equations, a time-varying electric field generates a magnetic field and vice versa. Therefore, as an oscillating electric field generates an oscillating magnetic field, the magnetic field in turn generates an oscillating electric field, and so on. These oscillating fields together form an electromagnetic wave. A quantum theory of the interaction between electromagnetic radiation and matter such as electrons is described by the theory of quantum electrodynamics.
What is the magnetic quantum number value for an element with n 1?
The magnetic quantum number value for an element with n=1 is the K shell.
What are the quantum numbers of calcium?
2s,6p,
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
What is a unit or quantum of light a particle of electromagnetic radiation that has zero res mass and carries a quantum of energy?
E=hv E= energy h=plank's constant v=is the frequency of the photon in question.
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.
