Excerpt from The Intensities of Some Hydrogen, Argon, and Helium Lines in Relation to Current and Pressure Lines in the spectra of luminous gases have long been known to vary in intensity with conditions in the excited gas. Some gases exhibit two quite different spectra, the primary and secondary, either of which may predominate according to the violence of the discharge causing them. Sparks between metallic electrodes give spectra richer in lines than arcs between the same metals. Additional capacity in circuit ...

Excerpt from The Intensities of Some Hydrogen, Argon, and Helium Lines in Relation to Current and Pressure Lines in the spectra of luminous gases have long been known to vary in intensity with conditions in the excited gas. Some gases exhibit two quite different spectra, the primary and secondary, either of which may predominate according to the violence of the discharge causing them. Sparks between metallic electrodes give spectra richer in lines than arcs between the same metals. Additional capacity in circuit intensifies certain lines, inductance weakens them. Similar variations might be cited in great number. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at ...
