R. W. WOOD 1 has described an interesting discharge tube which could be made to exhibit “either the spectrum of atomic hydrogen or molecular oxygen at will” on excitation by a high-frequency discharge ...
A set of five gas discharge tubes are arranged such that when they are touched with a Tesla coil, their characteristically colored emission spectra are seen. The Tesla coil can burn your skin on ...
A METHOD of exciting spectra by a high frequency discharge has been described by Wood and Loomis (NATURE, 120, 510; 1927), Clarke (NATTJUE, 120, 727; 1927), and others. The method consists of sending ...
