What Frequency Is the Schumann Resonance?
The Schumann resonance happens inside a set of spectrum peaks and valleys within the extraordinarily low-frequency wave portion of the Earth’s electromagnetic waves. The elemental frequency of the Schumann resonance sits at round 7.83 Hz, although this could fluctuate barely.
Whereas 7.83 Hz is usually cited because the Schumann resonance, it is extra correct to say that is the elemental frequency. In actuality, a number of Schumann resonance modes exist, with peaks occurring at roughly 7.83, 14.3, 20.8, 27.3, and 33.8 Hz. These are typically known as harmonics or overtones of the elemental frequency.
Historical past of the Schumann Resonance
The historical past of the Schumann resonance predates its discovery by Winfried Otto Schumann. Different contributors theorized concerning the resonance within the a long time main as much as Schumann’s seminal work.
Winfried Otto Schumann
Dr. Winfried Otto Schumann, a German physicist, found that low-frequency electromagnetic waves stay trapped contained in the Earth-ionosphere cavity. Instructing a course on atmospheric electrical energy at a college in Munich, the physician observed peculiar exercise occurring inside this cavity.
As Schumann studied the information, he noticed that low-frequency electromagnetic waves stay trapped inside the Earth-ionosphere cavity, forming standing waves. These waves created a elementary frequency of roughly 7.8 Hz, now referred to as the Schumann resonance.

Irish physicist George FitzGerald proposed the concept that the ambiance might act as conductor of electrical energy as early as 1893. Researchers credit score FitzGerald for uncovering the bottom types of Schumann resonances.
Scientists found the ionosphere in 1925, and G.N. Watson invented mathematical instruments to check spherical waveguides in 1918. Nonetheless, in-depth research about Earth’s electromagnetic waves didn’t happen till 1952-1954, when Schumann made the primary makes an attempt to measure the Earth’s resonant frequencies whereas working with H. L. König.
