What is radio frequency?

What Does radio frequency Mean

The concept of radio frequency is used to name the frequencies of the electromagnetic spectrum that are used in radiocommunications . To understand this notion, therefore, it is necessary to have some knowledge on this subject .

The electromagnetic spectrum refers to how the energy of electromagnetic waves is distributed . This spectrum is determined by the radiation that is emitted. The waves , on the other hand, suppose the propagation of this radiation, carrying energy.
This means that the electromagnetic spectrum ranges from the smallest wavelength radiation ( gamma rays ) to the longest wavelength radiation ( radio waves ). The frequency of the waves is measured in hertz .

Radio frequency, in short, is the part of the electromagnetic spectrum that ranges from 3 kilohertz to 300 gigahertz . These frequencies are used for military communications, navigation, radars, and AM and FM radio , to name a few.
Within the radio frequency it is also possible to establish different divisions according to the particularities of the frequencies. In this sense, we can talk from extremely low frequencies to extremely high frequencies , to other types of frequencies in between.
Amplitude modulated ( AM ) radio , for example, transmits in medium frequency. Radio frequency modulation ( FM ), on the other hand, carries out its transmission at very high frequencies. The different frequencies determine the range of the waves and the quality of the transmission, among other issues. The AM radios , in this sense, can reach their signals at greater distances compared to FM radios .
It is important to know that, in recent years, radio frequency has expanded its “services” and now, in addition to continuing to be used within the field of telecommunications, it has come to occupy a fundamental role in the field of medicine.
Thus, for example, at this time we speak of what is known as facial radiofrequency, which is a treatment that is performed on the face in order to make wrinkles that may exist in it disappear. Specifically, it is a lifting that consists of applying radio frequency energy to the face, with the clear objective that the resulting elevated temperature of 40º is capable of improving the immediate production of collagen and also favors elastin.
The result of this action is that, practically immediately, the person not only realizes that his wrinkles have disappeared or reduced to a minimum, but also that the sagging of his face has been eliminated and thus he already looks much younger. and toned.

Of this type of radio frequency other data of interest are highlighted such as these:

-It is a very safe treatment.

-It is called lifting without surgery, since it is not an invasive technique at all.

-The person who undergoes it does not have to be anesthetized.

-It can be applied on all skin types and on areas such as the neck and face, but also on the thighs and even on the abdomen.
