Emission spectrum: lines emitted from an atom.
Absorption spectrum: absorbed wavelengths of a molecule.

Emission spectra look at the wavelengths of light that the material gives off when energy is put into it.

How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
What is the Difference between spontaneous emission and stimulated emission any 5points?

Why is source modulation used in atomic absorption spectroscopy?
Source modulation is employed to distinguish between atomic absorption (an ac signal) and flame emission (a dc signal).
What is the difference between sunlight produced spectrum and hydrogen gas produced spectrum?
The spectrum of sunlight is continuous while for hydrogen is line spectrum (discontinuous)
What is the difference between ICP-AES and ICP-OES analysis?
The acronyms are synonyms. AES = Atomic Emission Spectroscopy OES = Optical Emission spectroscopy
What is the difference between an absorption and an emission spectrum?
Absorption spectrum is a gap in the overall spectrum. It happen when light makes an electron jump to a higher orbital and light energy is absorbed. Emission spectrum is light emitted at particular wavelengths (where the absorption spectrum gaps are). It happens when an electron falls from a higher orbital and emits light energy in doing so.
Explain the difference between the continuous spectrum of white light and the atomic emission spectrum of an element?
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.
How are absorption and emission lines produced in a stellar spectrum What information might absorption lines in the spectrum of a star reveal about a cloud of cool gas lying between us and the star?

What is the difference between emission and absorption?
Emission is something be spread out, while absorption is something being taken in.
What is the difference between emission and absorption in terms of what happens to an electron in an atom?
I dont know why did you think i ask wiki answers duhhh.................
If a star is moving away from you the absorption lines in its spectrum will?
If a star is moving away from you, the emission lines in its spectrum will be shiftedtoward longer wavelengths/lower frequency/the red end of the spectrum, since theyoriginate on the star itself.But there's no effect on the absorption lines, because those are caused by materialthat's unrelated to the star, and just happens to be in the line of sight between thestar and you.
Is the spacing between the lines in the spectrum of an element constant or does it vary?
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.
What are the similarities between emission and absorption spectra?
The lines are at the same frequencies
What is the difference between raman effect and flueroscence?
Raman scattering involves the SCATTERING of electromagnetic radiation by molecules, not atoms Fluorescence emission follows an absorption process
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
Narrow lines of colors with no light in between them are called what?
It is called an absorption spectrum.
How do scientists tell difference between elements?
There are many different tests. For example, if you burn some elements they give of light at very specific wavelengths, called an emission spectrum.
