Such a break is found in the spectrum of all remote objects (from the crowding of absorption lines creating an effect known as the «Lyman - alpha forest» before the Lyman - alpha spectral line at rest wavelength 121.6 nm).

They have also identified 10 spectral lines at each location that correspond to the lines created by glycine in the lab; before they had just two.

Two decades ago, astronomers found interstellar spectral lines at near - infrared wavelengths and said they likely arose from carbon - 60 molecules that had lost one electron each.

Not exact matches

Based on the wavelengths of spectral lines emitted by the luminous gas surrounding the black hole, the object is traveling at a speed of about 7.5 million kilometers per hour — a rate that would carry it from Earth to the moon in about 3 minutes.

In a valley in Idaho, a French team will analyse spectral lines in the corona, in part to support the infrared work of the CfA team, says Serge Koutchmy, an astronomer at the Institute of Astrophysics in Paris.

In a breakthrough, a group of researchers at the National Institute of Standards and Technology developed an on - silicon - chip laser source with outputs that consist of precisely defined and equally spaced optical lines within the mid-infrared spectral region.

The object studied here has a redshift of z = 5.913, i.e., the Lyman - alpha spectral line of hydrogen at 1216 angstrom (Å) at the rest frame is detected at 8406 Å, when the Universe was about one billion years old.

Yet so far, star formation historians have mostly relied on other indicators to write their histories: light at a particular frequency that is typically emitted when giant clouds collapse, heating up in the process and radiating away that heat in the form of specific spectral lines.

Working at the European particle physics laboratory, CERN, in Meyrin, Switzerland, they measured that «spectral line» to a precision of a few parts in 10 billion, as they report online today in Nature.

Note however that all the radiation in a spectral line is not at exactly a single frequency, but instead in a small range (band) of frequencies.

This is about the physical cross-sectional area of a CO2 molecule at the absolute peak of the spectral line.

So at the centers of the CO2 spectral lines the absorption is so large that the total cross section in a 1 meter path high of 1M ^ 2 of air is about 10M2 for the exact peak of the lines.

The solar spectrum of the sun consists of a roughly black body like thermal continuum spectrum, peaking at around 0.5 microns wavelength (plotted on wavelength scale; not wave number), and overlaid with the Fraunhoffer lines of either bright atomic spectral lines, due to elements in the sun, or dark atomic absorption lines, due to absorption of elements in the solar outer atmosphere.

If one were to take the model and plot a curve of emission versus wavelength rather than simply summing up the values (integrating over wavelength), it would show a spectral curve of a black body at 288.2 k with the absorption lines of the atmosphere dipping down to the point where there is a spectral curve for a lower temperature at which there is emission going on in the wavelength bands associated with ghg absorption.

Starting with the surface, each layer attenuates the BB spectrum with the ghg lines and will also emit at the ghg spectral line wavelengths but with a lower power level if the layer temperature is less.

Furthermore, on 22 April 1981 Mr. Gilbert Plass wrote that, whilst on the faculty at Johns Hopkins University during that period (1946 - 1955), he became interested in infrared spectroscopy — specifically in regards to pressure broadening of spectral lines (in explaining radiative transfer in the earth's atmosphere)-- and collaborated with Mr. John Strong in the above article because the need for [quote] «mathematical methods» [endquote], applicable to water, carbon dioxide and ozone, was obvious to him then.

The Wikipedia article you pointed to is about spectral lines, and at other points in the article they note that «spectral lines» applies to both absorption and emission.
