| 1890 A. E. Bostwick in Appleton's Ann. Cycl. 716/1 (Funk), Trouton..found that glass absorbs Hertzian vibrations with comparative rapidity. 1897 Rutherford in Phil. Trans. R. Soc. A. CLXXXIX. 1 They were also found to be a sensitive means of detecting electrical radiation from Hertzian vibrators at long distances from the vibrator. Ibid. 8 A detector for electrical waves was devised, which proved to be a sensitive means of detecting Hertzian waves. 1898 Daily News 3 May 5/3 The General Post Office..is also carrying out experiments in wireless Hertzian telegraphy. 1900 Jrnl. Soc. Arts XLVIII. 788/1 The sensation created in 1897 by Mr. Marconi's application of Hertzian waves. 1900 J. J. Fahie Hist. Wireless Telegr. 197 Sir William Crookes..was..the first to distinctly foresee the applicability of Hertzian waves to practical telegraphy. 1907 J. Erskine-Murray Handbk. Wireless Telegr. 36 The transmitter consisted of a Hertzian oscillator placed in the focal line of a parabolic mirror. 1908 J. A. Fleming Elem. Man. Radiotelegr. 132 An arrangement of two rods..with a spark gap in the centre constitutes the simplest form of linear radiator or Hertzian Oscillator for the production of damped electro-magnetic waves. 1914 R. Stanley Textbk. Wireless Telegr. 91 Using a suitable length of spark gap the discharge of this Hertzian open circuit is oscillatory. 1922 A. N. Whitehead Princ. Relativ. xiv. 117 Now consider the internal vibration of a molecule which radiates light of period T..as capable of being represented as the vibration of a variable electric Hertzian doublet with this period. 1940 Chambers's Techn. Dict. 412/2 Hertzian waves, electromagnetic waves having frequencies between zero and approximately ten thousand million cycles per second; especially those towards the upper limit of this range. 1971 Gloss. Electrotechnical Power Terms (B.S.I.) iii. vii. 7 Hertzian waves, electromagnetic waves having frequencies below those of infra-red waves. |
