Emission spectrum — The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted by the element s atoms or the compound s molecules when they are returned to a lower energy state. Each element s … Wikipedia
Atomic emission spectrum — The atomic emission spectrum of an element is the set of frequencies of the electromagnetic waves emitted by atoms of that element. Each atom s atomic emission spectrum is unique and can be used to determine if that element is part of an unknown… … Wikipedia
Photon — This article is about the elementary particle of light. For other uses, see Photon (disambiguation). Photon Photons emitted in a coherent beam from a laser Composition Elementary particle … Wikipedia
Emission (electromagnetic radiation) — In physics, emission is the process by which the energy of a photon is released by another entity, for example, by an atom whose electrons make a transition between two electronic energy levels. The emitted energy is in the form of a photon. The… … Wikipedia
Emission — may refer to: * Flue gas, also: ** Exhaust gas, flue gas occurring as a result of the combustion of a fuel * Emission of air pollutants * Emission (electromagnetic radiation), the process by which the energy of a photon is released by another… … Wikipedia
Emission spectroscopy — is a spectroscopic technique which examines the wavelengths of photons emitted by atoms or molecules during their transition from an excited state to a lower energy state. Each element emits a characteristic set of discrete wavelengths according… … Wikipedia
Spontaneous emission — is the process by which a light source such as an atom, molecule, nanocrystal or nucleus in an excited state undergoes a transition to the ground state and emits a photon. Spontaneous emission of light or luminescence is a fundamental process… … Wikipedia
Stimulated emission — In optics, stimulated emission is the process by which an electron, perturbed by a photon having the correct energy, may drop to a lower energy level resulting in the creation of another photon. The perturbing photon is seemingly unchanged in the … Wikipedia
Absorption spectrum — A material s absorption spectrum shows the fraction of incident electromagnetic radiation absorbed by the material over a range of frequencies. An absorption spectrum is, in a sense, the opposite of an emission spectrum.Every chemical element has … Wikipedia
Two-photon excitation microscopy — is a fluorescence imaging technique that allows imaging of living tissue up to a very high depth, that is up to about one millimeter. Being a special variant of the multiphoton fluorescence microscope, it uses red shifted excitation light which… … Wikipedia
Particle-Induced X-ray Emission — or Proton Induced X ray Emission (PIXE) is a technique used in the determining of the elemental make up of a material or sample. When a material is exposed to an ion beam, atomic interactions occur that give off EM radiation of wavelengths in the … Wikipedia
