French "Future Science" magazine recently published a short article on electromagnetic waves. It states that electromagnetic waves are ubiquitous in life, and that it is harmful to the human body. With the popularization of mobile phones, the doubling of base stations, and the launch of 3G, people are paying more and more attention to this issue.
As we all know, broadcasting can broadcast, television can broadcast, mobile phones can communicate, and satellite space communication can be realized, all due to the existence of electromagnetic waves. Radar, microwave ovens, wireless networks, and X-rays all operate through electromagnetic waves. The range of electromagnetic waves can be said to already include the entire world.
It should be noted that the visible light itself is a constituent of certain types of electromagnetic waves. Everyone may often not know that all people are bathed in complex electromagnetic waves. The stars produce waves, and our human body produces very weak waves. All operating appliances emit electromagnetic waves. Therefore, even if you do not have a mobile phone or a computer, you do not have a wireless network in your home. This does not mean that you are not in contact with electromagnetic waves. You are still bathed in electromagnetic waves at all times. As a simple example, if you turn on the radio, you will find that the electric wave is there. Although it is invisible, it operates invisibly.
The world of electromagnetic waves is nothing. There are long-wave, short-wave, high-energy waves, low-energy waves, strong waves, microwaves, visible, invisible, and invisible electromagnetic waves are much more than visible waves. Every kind of electromagnetic wave is actually a kind of energy, its volume is equal to zero, but the load is electric, the name is quantum, move with the speed of light in the vibration. Electromagnetic waves impact the ubiquitous electromagnetic wave atmosphere in the universe. These small quantums can be called photons in the light world. People define it in terms of intensity, wavelength, and frequency. Wavelengths are a bit like human footsteps. Wavelengths can be as short as one-billionth of a meter or as long as several million kilometers. The frequency can be compared with breathing or with heart rate. The greater the "footstep" of electromagnetic waves, the lower its frequency.
In fact, all the wavelengths of the electromagnetic waves we use are much longer than the wavelength of the light. Therefore, in theory, we use electromagnetic waves with a very low degree of danger. But the so-called danger of electromagnetic waves is not dangerous, but in fact it is all about your distance from it and its strength.
Here are some small examples of life. Which of the electric razors and cell phones are more harmful to the human body is actually hard to say. The intensity of the electromagnetic waves generated by an electric razor shave is much greater than that of a mobile phone. However, if you shave once or twice a day at most, it will have little effect. It is still controversial whether mobile phones are harmless or not. However, telecommunication health experts usually recommend that people do not hang their phones on their ears while they are on the phone. The distance between the mobile phone and the body is the most important. If possible, it is best equipped with a headset (Bluetooth). Do not, because the strength of electromagnetic waves used by Bluetooth technology is much greater than the electromagnetic waves generated by ordinary mobile phones).
Pay attention to electromagnetic waves and pay attention to healthy life!
