  2. Schumann resonances - Wikipedia

    en.wikipedia.org/wiki/Schumann_resonances

    A simplified artistic animation of Schumann resonance in Earth's atmosphere. The Schumann resonances ( SR) are a set of spectrum peaks in the extremely low frequency portion of the Earth 's electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity ...

  3. Extremely low frequency - Wikipedia

    en.wikipedia.org/wiki/Extremely_low_frequency

    The fundamental Schumann resonance is at approximately 7.83 Hz, the frequency at which the wavelength equals the circumference of the Earth, and higher harmonics occur at 14.1, 20.3, 26.4, and 32.4 Hz, etc. Lightning strikes excite these resonances, causing the Earth–ionosphere cavity to "ring" like a bell, resulting in a peak in the noise ...

    Technical University of Munich. Doctoral advisor. Engelbert Arnold. Doctoral students. Fritz Borgnis. Winfried Otto Schumann (May 20, 1888 – September 22, 1974) was a German physicist and electrical engineer who predicted the Schumann resonances, a series of low-frequency resonances caused by lightning discharges in the atmosphere.

  5. Earth–ionosphere waveguide - Wikipedia

    en.wikipedia.org/wiki/Earth–ionosphere_waveguide

    Earth–ionosphere waveguide. The Earth–ionosphere waveguide [1] is the phenomenon in which certain radio waves can propagate in the space between the ground and the boundary of the ionosphere . Because the ionosphere contains charged particles, it can behave as a conductor. The earth operates as a ground plane, and the resulting cavity ...

  6. Resonance - Wikipedia

    en.wikipedia.org/wiki/Resonance

    Resonance can also be undesirable, leading to excessive vibrations or even structural failure in some cases. All systems, including molecular systems and particles, tend to vibrate at a natural frequency depending upon their structure; this frequency is known as a resonant frequency or resonance frequency.

  7. Atmospheric electricity - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_electricity

    Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet ). The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit. Atmospheric electricity is an interdisciplinary topic with a long history, involving ...

  9. Robert Schumann - Wikipedia

    en.wikipedia.org/wiki/Robert_Schumann

    Robert Schumann[ n 1] ( German: [ˈʁoːbɛʁt ˈʃuːman]; 8 June 1810 – 29 July 1856) was a German composer, pianist, and music critic of the early Romantic era. He composed in all the main musical genres of the time, writing for solo piano, voice and piano, chamber groups, orchestra, choir and the opera. His works typify the spirit of the ...
