hertzian wave การใช้

• Early on after their discovery, radio waves were referred to as " Hertzian waves ".
• The discovery of these " Hertzian waves " ( radio waves ) prompted many experiments by physicists.
• The history of the Hertzian waves shows us the ubiquity of these vibrations in the external world, imperceptible to our senses.
• These papers were read by English physicist Oliver Lodge who saw this as a way to build a much improved Hertzian wave detector.
• That same year Italian inventor Guglielmo Marconi demonstrated a wireless telegraphy system using Hertzian waves ( radio ), based on a coherer.
• At that time, the word'coherer', coined by Lodge, was used in the English-speaking world for Hertzian wave receivers or detectors.
• Wireless telegraphy came to mean Morse code transmitted by radio waves ( electromagnetic waves ), initially called " Hertzian waves ", discovered by Heinrich Hertz in 1886.
• Over several years starting in 1894 the Italian inventor Guglielmo Marconi built the first complete, commercially successful wireless telegraphy system based on airborne Hertzian waves ( radio transmission ).
• Lodge set up a demonstration on the quasi optical nature of " Hertzian waves " ( radio waves ) and demonstrated their similarity to light and vision including reflection and transmission.
• In May 1895, after reading about Lodge's demonstrations, the Russian physicist Alexander Popov built a " Hertzian wave " ( radio wave ) based lightning detector using a coherer.
• The apparent need for a propagation medium for such Hertzian waves can be seen by the fact that they consist of perpendicular electric ( E ) and magnetic ( B or H ) waves.
• Tesla had studied radio waves early on, at the time called " Hertzian waves " after their discovery by Hertz, and come to the conclusion that the theory on them was incorrect.
• Many experimenters used the spark gap setup to further investigate the new " " Hertzian wave " " ( radio ) phenomenon, including Oliver Lodge and other " Maxwellian " investigators.
• In 1992, the Prime Minister of Mauritius said that he was firmly opposed to opening the hertzian waves to foreign television, and that his government " would not accord this liberty to foreigners ".
• By 1910 communication by Hertzian waves was universally referred to as " radio ", and the term wireless telegraphy has been largely replaced by the more modern term " "'radiotelegraphy "'".
• George Minchin noticed the Branly tube might be reacting to Hertzian waves the same way his solar cell did and wrote the paper " " The Action of Electromagnetic Radiation on Films containing Metallic Powders " ".
• He then completed his studies at Yale's Sloane Physics Laboratory, earning a Doctorate in 1899 with a dissertation on the " Reflection of Hertzian Waves from the Ends of Parallel Wires ", supervised by theoretical physicist Willard Gibbs.
• Hertz's proof of the existence of airborne electromagnetic waves led to an explosion of experimentation with this new form of electromagnetic radiation, which was called " Hertzian waves " until around 1910 when the term " radio waves " became current.
• Between 1890 and 1892 physicists such as John Perry, Frederick Thomas Trouton and William Crookes proposed electromagnetic or Hertzian waves as a navigation aid or means of communication, with Crookes writing on the possibilities of wireless telegraphy based on Hertzian waves in 1892.
