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. These "fingerprints" can be compared to the previously collected "fingerprints" of atoms and molecules, and are thus used to identify the atomic and molecular components of stars and planets, which would otherwise be impossible. 1050lb 3mm Braided Spectra Extra Heavy Duty Speargun Shooting Line/Survival Utility Cord - Super Strong, Cut/Abrasion/UV Resistant, Low Stretch. 4.7 out of 5 stars. 85.

Line spectra

Line Spectra. Spectral lines are fundamentally broadened by the quantum mechanical natural width and by the integrated effect of thermal motions by individual atoms along a line-of-sight. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003. Related terms: Wavelength; Energy Levels; Continuum; Collision; Spectrometer; Photon; Ion; X Ray Noun 1. line spectrum - a spectrum in which energy is concentrated at particular wavelengths; produced by excited atoms and ions as they fall back to a lower energy level spectrum - an ordered array of the components of an emission or wave Line spectra are sharp lines of definite wavelengths.

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 1913, a Danish physicist, Niels Bohr (1885–1962; Nobel Prize in Physics, 1922), proposed a theoretical The Energy States

Emission-line spectra Low-density clouds of gas floating in space will emit emission lines if they are excited by energy from nearby stars. Planetary nebulae, for example, are the remnants of stars which have gently pushed their outer envelopes outwards into space.

These lines came to be known Line spectra. These, as would be imagined, are spectra that appear as specific discrete lines on a background. They may be either emission or absorption.

Emission-line spectra Low-density clouds of gas floating in space will emit emission lines if they are excited by energy from nearby stars. Planetary nebulae, for example, are the remnants of stars which have gently pushed their outer envelopes outwards into space. An absorption line spectrum is produced when cool gas lies between a continuum source and us; the specific wavelengths absorbed by the atoms in the gas are removed from the light that comes to us.

line spectrum. n. A spectrum produced by a luminous gas or vapor and appearing as distinct lines characteristic of the various elements constituting the gas.

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. Some spectra may deviate considerably from the depictions pictured here. We are photographing as many element spectra as possible in order to confirm the line intensities of the source data.

spectrum provides a useful invariant. This book gives the standard elementary material on spectra in Chapter 1. Important applications of graph spectra involve the largest or second largest or smallest eigen-value, or interlacing, topics that are discussed in Chapters 3–4. Afterwards, special

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. The nitrogen spectrum shown above shows distinct bands throughout the visible range. The blue lines in the above were brightened for greater visibility in the image. This is its atomic line emission spectra. Electrons exist in distinct energy levels in the atom. They can move up in energy by absorbing a photon or move down in energy by emitting a photon.

This video introduces and explains both emission line spectra and absorption line spectra for A Level Physics.Why are fireworks coloured, how can we tell wha Line/Spectrum Fitting¶. One of the primary tasks in spectroscopic analysis is fitting models of spectra. This concept is often applied mainly to line-fitting, but the same general approach applies to continuum fitting or even full-spectrum fitting.
