Dr. Wollaston, in 1802, as we have seen stood upon the threshold of spectroscopy without knowing it.
Celestial photography, photometry and spectroscopy sum up its fields of activity.
Simple as it is in its broad outlines, spectroscopy is, in reality, one of the most intricate branches of modern science.
His most important work was concerned with the conduction of heat and with spectroscopy.
In the earliest days of spectroscopy the spectra of the stars were classified according to their visual spectra.
It is to Sir William Huggins, however, that we are indebted for the application of the principle to spectroscopy.
In spectroscopy, Blopolsky has sought to determine the period of rotation of Venus on her axis.
Then came astrophysics, including photography, spectroscopy and photometry.
In the early days of spectroscopy many doubters said, What good is all this?
The basis of spectroscopy is the prism, which separates sunlight into seven colors and projects a band of light called a spectrum.
spectroscopy spec·tros·co·py (spěk-trŏs'kə-pē)
The study of spectra, especially experimental observation of optical spectra.
The analysis of spectra, especially light or mass spectra, to determine properties of their source. ◇ In light or optical spectroscopy, the spectrum of a light source is analyzed through a spectroscope to determine atomic composition of a substance. In astronomy, phenomena such as red shift can also be analyzed. ◇ In mass spectroscopy, a spectroscope is used to determine the composition of ions or charged molecules in a sample. Spectroscopy is also called spectrography. See also atomic spectrum, spectroscope.
The branch of science devoted to discovering the chemical composition of materials by looking at the light (and other kinds of electromagnetic radiation) they emit. Scientists use spectroscopy to determine the nature of distant stars and galaxies as well as to identify and monitor the production of products in factories.
