WHAT IS RADIOFREQUENCY?

A type of electromagnetic wave.

Electromagnetic waves are able to travel through the void, as opposed to the mechanical waves that need a material medium to do so.

As its name implies, electromagnetic radiation is comprised of electric and magnetic charge. There is an enormous range of waves and they are differentiated by their frequency.

Two important features of electromagnetic radiations are:

• Photonic energy.
• Propagation speed.

(The transmission speed of these radiations is also the same, 300,000 Km/s, without considering its frequency or power).

Electromagnetic radiation is understood as the transport of energy through particles (quanta) through space. These particles are displaced following a wave-like motion which gives rise to a wave, transporting electric and magnetic energy.

The particles (quanta) change according to their electric charge and this conditions their wavelength, giving different types of electromagnetic radiation according to those charges. The electromagnetic phenomena are described more easily by whether they are associated or not to photons or elementary particles. This is what is defined in physics as wave-particle duality of electromagnetic radiation. The higher an electromagnetic wave, the higher energy of its associated particle. Photons associated to x-rays and gamma rays have a high energy content, while those associated to extremely low radiations have very low energy content. Ultraviolet radiation, visible radiation, infrared radiation, microwaves and radiofrequency are between these two extremes. The quanta associated to these radiations has an intermediate energetic charge.

Light is a form of electromagnetic radiation in which the particles are photons, the energy is transmitted by photons. Within the spectrum of electromagnetic radiation, the laser occupies the wavelength range lies between the ultraviolet and infrared light (between 280 Nm. And one million Nm.). To the right would be in shorter wavelength, gamma rays, and to the left would Microwaves and Radiofrequency.
