The meaning of EMISSION SPECTRUM is an electromagnetic spectrum that derives its characteristics from the material of which the emitting source is made and from the way in which the material is excited.
electromagnetic energy, such as light, passes through a substance and excites its atoms. The excited atoms give off energy in the form of light. Because each type of atom gives off light having a unique range of colors, the emission spectrum can be used to determine the substance's chemical...
spectrum analysis (redirected from Emission spectrochemical analysis)Also found in: Thesaurus, Encyclopedia. spectrum analysis n (General Physics) the analysis of a spectrum to determine the properties of its source, such as the analysis of the emission spectrum of a substance to determine the ...
The meaning of SPECTROMETER is an instrument used for measuring wavelengths of light spectra. How to use spectrometer in a sentence.
In chemistry, an emission spectrum refers to the range ofwavelengthsemitted by anatomor compound stimulated by either heat or electric current. An emission spectrum is unique to eachelement. The emission spectrum of burning fuel or other molecules may also be used to example its composition. ...
an ordered array of the components of an emission or wave The several colored and other rays of which light is composed, separated by the refraction of a prism or other means, and observed or studied either as spread out on a screen, by direct vision, by photography, or otherwise. ...

This state is unstable, so the electrons drop down to lower energy levels they give off energy in the form of a photon of electromagnetic radiation. When the light given off is put through a prism, it is separated into the different wavelengths, producing an emission spectrum. What are line...
A spectrum is defined as the characteristic wavelengths of electromagnetic radiation (or a portion thereof) that is emitted or absorbed by an object or substance,atom, ormolecule. Plural:Spectra Example Examples of a spectrum include the rainbow, the emission colors from the Sun, and the infrared...
Is absolute count of emission spectrum meaningful? I am using Renishaw confocal Raman microscope to do photoluminescence spectroscopy of some polymer inside microchannel. When I fix the laser power and exposure time, the absolute count of intensity will change from time to time even for the same ...
