what is the electromagnetic frequency of the earth?
234993
The Earth behaves like a gigantic electric circuit. Its electromagnetic field surrounds and protects all living things with a natural frequency pulsation of 7.83 hertz on average — the so-called “Schumann resonance,” named after physicist Dr. Winfried Otto Schumann, who predicted it mathematically in 1952.

The lowest frequency portion of the electromagnetic spectrum is designated as “radio,” generally considered to have wavelengths within 1 millimeter to 100 kilometers or frequencies within 300 GHz to 3 kHz. There is a wide range of subcategories contained within radio including AM and FM radio.

432 Hz. The magic number everybody is talking about. It is said to be the natural frequency of the universe, to have cosmic healing powers and to attract masses of audience to our music.

Electromagnetic waves are transverse waves. The wave number is k = 2π/λ, where λ is the wavelength of the wave. The frequency f of the wave is f = ω/2π, ω is the angular frequency.
931786
The number of times the electromagnetic field undergoes a complete cycle per unit time is called the frequency. The speed with which radiation can travel is limited, and moreover, radiation of all wavelengths travel at a single speed. This is referred to as the speed of light, universally denoted by the symbol c.

*8. The range of infrared radiation from Earth is 6 to 22 microns. Each greenhouse gas and water vapor absorbs radiation from different areas of the electromagnetic spectrum. Carbon dioxide and water absorb long wave radiation from 12 to 19 microns.

Electromagnetic waves are produced by the movement of charged particles. High-frequency electromagnetic waves carry more energy than low-frequency ones. Frequency is determined by the amount of wavelengths that pass in one second.

The relationship between the frequency (the number of wave crests that pass by a certain point in a given amount of time) and wavelength for electromagnetic waves is defined by the formula, c = λ f, where c is the speed of light, λ the wavelength in meters, and f equals the frequency in cycles per second.

The full range of electromagnetic radiation is called the electromagnetic spectrum. From longest to shortest wavelengths, it includes radio waves, microwaves, infrared light, visible light, ultraviolet light, X rays, and gamma rays.

Electromagnetic Spectrum. The electromagnetic spectrum (EMS) is the general name given to the known range of electromagnetic radiation. Wavelengths increase from approximately 10-18 m to 100 km, and this corresponds to frequencies decreasing from 3 × 1026 Hz to 3 ×103 Hz.

Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm. ... Electromagnetic waves with shorter wavelengths and higher frequencies include ultraviolet light, X-rays, and gamma rays.

Electromagnetic waves are a form of energy waves that have both an electric and magnetic field. Electromagnetic waves are different from mechanical waves in that they can transmit energy and travel through a vacuum. Electromagnetic waves are classified according to their frequency.

Most electromagnetic radiation from space is unable to reach the surface of the Earth. Radio frequencies, visible light and some ultraviolet light makes it to sea level. Astronomers can observe some infrared wavelengths by putting telescopes on mountain tops.
128040
Electromagnetic waves exist from 0.00001 Hz up to 1000's of terahertz, and probably waves beyond even these limits. Electromagnetic waves are generated by accelerating (or oscillating) charges. The frequency of the wave simply depends on how fast the charge is oscillating.
865932
Electromagnetic radiation with wavelengths between roughly 400 and 700 nm is called visible light because these are the waves that human vision can perceive. This is also the band of the electromagnetic spectrum that most readily reaches Earth's surface.
726539
Other technologies produce intermediate frequency (IF) fields with frequencies from 300 Hz to 10 MHz and radiofrequency (RF) fields with frequencies of 10 MHz to 300 GHz. The effects of electromagnetic fields on the human body depend not only on their field level but on their frequency and energy.
1109729
Electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies.
