Infrared radiation is a type of electromagnetic and thermal radiation, with a greater wavelength than visible light, however it is shorter than that of microwaves. For this reason, it has a lower frequency than visible light, but higher than microwaves. Its range of wavelengths ranges from 0.7 to 1000 microns. Infrared radiation is produced by the action of any body whose temperature is greater than 0 Kelvin, which is equal to −273.15 degrees. Celsius. Usually astronomersThey divide the infrared part of the electromagnetic spectrum into three different zones, which are: the near infrared (0.7 - 5 microns), the mid-infrared (it ranges between 5 - 30 microns) and the far infrared (it is located between 30 - 1000 microns).
Those lines that are produced in the place where a certain type of energy is generated, which propagates in a certain direction, is called lightning. Infrared, on the other hand, is also considered an adjective that refers to radiation whose wavelength exceeds red.
For this reason, infrared rays represent a class of electromagnetic radiation with a wavelength that is greater than the wavelength of light that can be seen, but less than the wavelength that microwaves present.
William Herschel, a renowned astronomer, credited with discovering the first planet since the Ancient Ages (Uranus) and also studying sunspots, was the first to discover a form of light other than optical light. Through an experiment conducted in the year 1800, Herschel used a glass prism in order to scatter the sunlight from a rainbow. After that he proceeded to measure the temperature of each color of visible light, making annotations of them.
The result was that when he placed the thermometer beyond red, in an area where there was no light to the naked eye, the thermometer marked a high temperature, that is, as if there were radiation incident on that region, which the naked eye could not visualize.
In general, it is not dangerous, especially if it is produced naturally by physical processes. However, it should be noted that any form of radiation, including visible light or radio waves, can be potentially dangerous, if they are highly concentrated in a very narrow beam of great power. Today people live immersed in infrared radiation, since it is nothing else but heat. But of course.
