The part of the electromagnetic spectrum used in radio communications is called radio frequency.
The concept of radio frequency is used to name the frequencies of the electromagnetic spectrum that are used in radio communications . To understand this notion, therefore, it is necessary to have certain 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. Waves , for their part, involve the propagation of this radiation, carrying energy.
This means that the electromagnetic spectrum ranges from radiation with the smallest wavelength ( gamma rays ) to radiation with the longest wavelength ( radio waves). The frequency of waves is measured in hertz .
What is radio frequency
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, radar, and AM and FM radio, to name a few possibilities.
Within radio frequency it is also possible to establish different divisions according to the particularities of the frequencies. In this sense, we can talk about extremely low frequencies to extremely high frequencies , passing through other types of frequencies in between.
Amplitude modulated ( AM ) radio , for example, transmits at medium frequencies. Frequency modulated radio ( FM ), on the other hand, transmits at a very high frequency. The different frequencies determine the range of the waves and the quality of the transmission, among other issues. AM radios , in this sense, can reach greater distances with their signals compared to FM radios .
The different radio frequencies determine the transmission quality and the range of the waves.
Its use in medicine
It is important to know that, in recent years, radiofrequency has expanded its "services" and now, in addition to continuing to be used within the field of telecommunications, it has come to play a fundamental role in the field of medicine.
Thus, for example, at the moment we are talking about what is known as facial radiofrequency, which is a treatment that is performed on the face in order to make any wrinkles that may exist on it disappear. Specifically, it is a lifting that consists of applying radiofrequency 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 their wrinkles have disappeared or been reduced to a minimum but that the flaccidity of their face has also been eliminated and thus a much younger image appears. and toned.
Other data of interest such as these are highlighted from this type of radio frequency:
-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 types of skin and on areas such as the neck and face, but also on the thighs and even the abdomen.
