On the atomic level what causes an electromagnetic wave to be emitted?

On any level the movement of charge carriers (electrons, protons etc) cause EM radiation to be emitted. Gamma rays are also emitted as the result of some radioactive decay reactions All radioactive decay reactions produce EM radiation of some kind because they involve the movement of charge carriers such as the ejection of alpha particles (double positive charge).

How does electromagnetic radiation originate?
As it is a form of energy, it cannot be said to originate in any normal sense - energy is neither destroyed nor created. The other problem with your question is that because the electromagnetic spectrum covers all forms of radiated wave energy, there is no simple answer. As a very simple starting point, all forms of EMR can be generated as a result of a change in energy of matter. For instance, visible light, UV and other wavelengths can be emitted when an electron changes energy level in an atom or in a plasma, infrared can be emitted when an atom drops in temperature, X-rays can be emitted when high energy electrons are absorbed by a solid metal target,
How is an electromagnetic wave produced?
electromagnetic waves are produced by the motion of electrically charged particles. electromagnetic waves are also called electromagnetic radiation because they radiate from electrically charged particles.
What is difference between atomic energy and nuclear energy?
Atomic energy is really a misnomer for nuclear energy. It is the fissioning of the nucleus which causes energy to be released. At the atomic level we are dealing with chemical reactions, but in the early days people did talk of atomic power and atomic bombs.
How much faster are electromagnetic wave than sound waves?
Electromagnetic waves in vacuum move about 881 thousand timesas fast as sound in sea-level air.
How do you generate light?
Light is generated when photons are emitted from an atom. This occurs when an electron on one energy level of an atom falls to a lower energy level.
Working principle of atomic emission spectroscopy?
An emission spectrum is the spectrum of frequencies of the electromagnetic radiation emitted (by an atom or molecule) during a transition from a high energy to a low energy level.
How is the light of an emission spectrum of an element produced?
Basically, energy is emitted when an electron falls from a higher energy level to a lower energy level. Such energy is emitted as electromagnetic waves, which in certain cases can be visible light.
What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
How is electromagnetic spectrum related to electrons?
No direct relation; electromagnetic waves are transmitted by photons. However, electromagnetic waves are often caused by the acceleration of electric charges, and those charges are usually electrons. Also, electromagnetic waves are emitted and absorbed when an electron (in an atom) changes to another energy level.
Quanta of light emitted from 1 electron drops from the 7th to 2nd energy level?
What atom? Need Z (atomic ) number.
What is the Balmer Series?
The Balmer series is a section of the hydrogen atomic emission line spectrum. They show the wavelengths of light emitted when electrons transition back to the n = 2 quantum level.
Why do you see color when you burn a metallic salt?
During the burning process, electrones shift between different energy levels. Returning from a higher to a lower energy level, electromagnetic waves (light) are emitted. Depending on what substance was burned, waves of different length are emitted, i.e. light of different color is radiated.
What is an atomic clock?
An atomic clock is a reference clock whose operation is based on an atomic process, such as the frequency of electromagnetic radiation associated with a specific energy-level transition in an element such as caesium.
When an electron drops from a higher energy state to a lower energy state?
A photon is emitted when an electron falls from a higher to lower orbital. A photon is an elementary particles, the quantum of light and all other forms of electromagnetic radiation.
What is atomic level?
The atomic level is the finest grain of aggregation summarized by a dimensional data model. When applied to dimensions, the atomic level refers to the discrete values the dimension may assume. When applied to a dataset, the atomic level is the cell created by the intersection of all dimensions at the atomic level. The atomic level is the lowest level of detail normally stored in a multi-dimensional database.
What happens to an atomic level when an element melts?
The atomic level is unchanged.
When an electron drops from level 5 to level 1 a photon is emitted in what region?
Ultraviolet
