Abstract

The spectra from hydrogen, oxygen and air excited by currents of the frequency of the order of 106 alternations per second produced by an oscillating fifty-watt electron tube were photographed with a grating spectrograph in the spectral region from 5000 A to 3500 A. These spectra were found to be identical with the spectra of the same gas stimulated by sixty-cycle current of the same strength as the radio frequency current.
