What is Electromagnetic Radiation? Top 10 facts about the world. Electromagnetic radiation is a term used to describe a stream of energy-bearing particles that travels outward from an electromagnetic source. The energy in these streams can vary extensively in power, and is measured by the electromagnetic spectrum.

Electromagnetic waves An electromagnetic wave (such as a radio wave) propagates outwards from the source (an antenna, perhaps) at the speed of light. What this means in practice is that the source has created oscillating electric and magnetic fields, perpendicular to each other, that travel away from the source.

There is a simple relationship between the wavelength and frequency of a particular colour of light and the speed of light:

Electromagnetic radiation Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vacuum. The oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The wavefront of electromagnetic waves emitted from a point source (such as a lightbulb) is a sphere.

Electromagnetic spectrum The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end.

How are Radio Waves Blocked? Radio waves are electromagnetic waves and travel at the speed of light which is 186, 280 miles per second (983,558,400 feet per second). The voltage in a radio wave alternates back and forth between plus and minus many times per second and we call this the frequency of the radio wave in cycles per second.

Battery and Energy Technologies Electromagnetic radiation has the following interesting properties. 1  It can be found in nature or be man-made. 2  It does not require a medium for propagation. 3  It travels with the speed of light.  It carries energy as it propagates. The higher the frequency, the higher the energy associated with the wave.

- The millimeter-wave region of the electromagnetic spectrum is usually considered to be the range of wavelengths from 10 millimeters (0.4 inches) to 1 millimeter (0.04 inches).This means millimeter waves are longer than infrared waves or x-rays, for example, but shorter than radio waves or microwaves.The millimeter-wave region of the electromagnetic spectrum corresponds to radio band frequencies of 30 GHz to 300 GHz and is sometimes called the Extremely High Frequency (EHF) range.adar is another important use of millimeter waves, which takes advantage of another important property of millimeter wave propagation called beamwidth. Beamwidth is a measure of how a transmitted beam spreads out as it gets farther from its point of origin.

Most of the radio part of the EM spectrum falls in the range from about 1 cm to 1 km, which is 30 gigahertz (GHz) to 300 kilohertz (kHz) in frequencies.The radio is a very broad part of the EM spectrum.adio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light.

- A radio wave can have an energy of around 4 x 10-10 eV-a gamma-ray can have an energy of 4 x 109 eV. That's an energy difference of 1019 (or ten million trillion) eV! We already know that when we talk about wavelength, we are talking about the distance between two peaks of a wave.lectromagnetic waves can be described by their wavelengths, energy, and frequency. All three of these things describe a different property of light, yet they are related to each other mathematically.

Introduction All electromagnetic radiation travels in a vacuum at a constant velocity: c = 3.00 x 108 m/s, the speed of light. For light waves, the frequency and wavelength are inversely related, and their product is equal to velocity: ν λ= c. Frequency is generally measured in Hertz-cycles per second (written 1/sec or sec-1).

Communications System Actually, radio waves travel very quickly through space. Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light. The speed of light is a little less than 300,000 km per second. At that speed, a beam of light could go around the Earth at the equator more then 7 times in a second.
