Lyman series: see spectrum spectrum, arrangement or display of light or other form of radiation separated according to wavelength, frequency, energy, or some other property. Beams of charged particles can be separated into a spectrum according to mass in a mass spectrometer (see mass ..... Click the link for more information. .

Viewing hydrogen gas over the entire sky, a SOHO detector known as Solar Wind Anisotropies (SWAN) records a wavelength of ultraviolet radiation called Lyman alpha. Together, the clouds create a thicket of absorption lines -- called the Lyman alpha forest -- within the spectra of quasars. He believes the 656-nm figure, which represents the Lyman alpha radiation of hydrogen, is a good measure of the actual photosphere of the supernova. |
