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
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
Emission (Physik) — Als Emission (von lat. emittere aussenden) bezeichnet man in der Physik zumeist die Aussendung von Energie oder Materie in Form von Wellen oder Teilchen. Emission von Photonen: Aussendung elektromagnetischer Wellen. Elektronenemission bezeichnet… … Deutsch Wikipedia
Emission nebula — An emission nebula is a cloud of ionized gas ( i.e. a plasma) emitting light of various colors. The most common source for ionization are high energy photons emitted from a nearby hot star. Among the several different types of emission nebula are … Wikipedia
