Hydrogen Spectral Series
The emission spectrum of atomic hydrogen is divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed spectral lines are due to electrons moving between energy levels in the atom. The spectral series are important in astronomy for detecting the presence of hydrogen and calculating red shifts. Further series were discovered as spectroscopy techniques developed.

Famous quotes containing the words hydrogen, spectral and/or series:
“All you of Earth are idiots!... First was your firecracker, a harmless explosive. Then your hand grenade. They begin to kill your own people a few at a time. Then the bomb. Then a larger bomb, many people are killed at one time. Then your scientists stumbled upon the atom bomb—split the atom. Then the hydrogen bomb, where you actually explode the air itself.”
—Edward D. Wood, Jr. (1922–1978)
“How does one kill fear, I wonder? How do you shoot a spectre through the heart, slash off its spectral head, take it by its spectral throat?”
—Joseph Conrad (1857–1924)
“The woman’s world ... is shown as a series of limited spaces, with the woman struggling to get free of them. The struggle is what the film is about; what is struggled against is the limited space itself. Consequently, to make its point, the film has to deny itself and suggest it was the struggle that was wrong, not the space.”
—Jeanine Basinger (b. 1936)
