Augusto RighiBorn 27 Aug 1850; died 8 Jun 1920 at age 69.Italian physicist who showed that radio waves displayed characterics of light wave behaviour in the manner of reflection, refraction, polarization and interference. Thus the nature of radio waves was similar to light, but with the difference of greater wavelength and a part of the same electromagnetic spectrum as light. He discovered magnetic hysteresis (1880). He was the first person to generate microwaves, and opened a whole new area of the electromagnetic spectrum to research and subsequent application. By 1900 also began work on X-rays. In 1903 he wrote the first paper on wireless telegraphy. His improvements on the work of Hertz were passed along to Guglielmo Marconi, who studied in Righi's laboratory. |
