A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules.

They can move up in energy by absorbing a photon or move down in energy by emitting a photon. What does line-spectrum mean? A spectrum that consists of narrow, brightly colored, parallel lines on a dark background, emitted by a low-pressurized LINE SPECTRA's profile including the latest music, albums, songs, music videos and more updates. 6.3: Line Spectra and the Bohr Model Line Spectra. Although objects at high temperature emit a continuous spectrum of electromagnetic radiation, a different Bohr's Model.

In spectrum …other hand, is called a line spectrum because only a few wavelengths are emitted. These wavelengths appear to be a series of parallel lines because a slit is used as the light-imaging device. Line spectra are characteristic of the elements that emit the radiation. Line spectra are also called atomic… Read More; electromagnetic radiation 2015-12-31 · Line Spectra Emission Line Spectrum. The atom is first excited by a colliding electron.

One way for atoms… 8.3 Line spectra: ions and spectral lines.

A discontinuous spectrum characteristic of excited atoms, ions, and certain molecules in the gaseous phase at low pressures. If an electric arc or spark between metallic electrodes, or an electric discharge through a low-pressure gas, is viewed through a spectroscope, images of the spectroscope slit are seen in the characteristic colors emitted by the atoms or ions present. Disclaimer: Spectra that have not been photographed might not look exactly like the image above.

Visible Spectra of the Elements. UPDATE: I have procured samples of most of the elements and added photos of their spectra, in order to verify the relative intensities of the brightest lines. The line intensities from my source data have been adjusted accordingly.
