The global electromagnetic resonance phenomenon is named after physicist Winfried Otto Schumann who predicted it mathematically in 1952. Schumann resonances are the principal background in the part of the electromagnetic spectrum [2] from 3 Hz through 60 Hz [3] and appear as distinct peaks at extremely low frequencies around 7.83 Hz (fundamental), 14.3, 20.8, 27.3, and 33.8 Hz.
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 ...
The following list illustrates various frequencies, measured in hertz, according to decade in the order of their magnitudes, with the negative decades illustrated by events and positive decades by acoustic or electromagnetic uses.

Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere. [1]: 26‑1 As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering. [2]
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.

A typical performance lasts approximately 18–19 minutes. In the months leading up to working on this symphony Schumann had been studying and transcribing the music of Beethoven, whose influence can be heard in the first two movements, particularly the use of short motives rather than full-blown melodies in the first movement and the solemn rhythms of the second, which are reminiscent of the ...
See media help. The Piano Sonata No. 1 in F♯ minor, Op. 11, was composed by Robert Schumann from 1833 to 1835. He published it anonymously as "Pianoforte Sonata, dedicated to Clara by Florestan and Eusebius". Eric Frederick Jensen describes the sonata as 'the most unconventional and the most intriguing' of Schumann's piano sonatas due to its ...
Robert Schumann. This list of compositions by Robert Schumann is classified into piano, vocal, orchestral and chamber works. All works are also listed separately, by opus number. Schumann wrote almost exclusively for the piano until 1840, when he burst into song composition around the time of his marriage to Clara Wieck. The list is based on ...
