Difference Between Emission And Absorption Spectra

6 Difference Between Emission And Absorption Spectra

S.NO.	Emission  Spectra	Absorption Spectra
1.	Emission spectra are the wavelengths of light emitted by an atom or molecule.	Absorption spectra are the wavelengths of light absorbed by an atom or molecule.
2.	Emission spectra are produced when energy is released by an atom or molecule.	Absorption spectra are produced when energy is absorbed by an atom or molecule.
3.	Emission spectra are produced by transitions between energy levels in an atom or molecule.	Absorption spectra are produced by transitions between energy levels in an atom or molecule.
4.	Emission spectra are typically measured by spectrometers, while	Absorption spectra are typically measured by spectrophotometers.
5.	Emission spectra are used in the analysis of gases, flames, and the surface of stars.	Absorption spectra are used in the analysis of liquids, solids, and gases.
6.	Emission spectra are typically used to identify the elements present in a sample.	Absorption spectra are used to determine the concentration of a substance in a sample.
