Infrared heaters (emitters), although there are in the market for quite a long time, but not everyone knows and understands the principle of their actions. What is it – infrared radiation? Where else can use it? Infrared radiation: a little history. Discovered infrared radiation in 1800 by Englishman William Herschel. According to Dr. Mark Hyman, who has experience with these questions. He found that in the resulting spectrum with a prism beam of the sun, are abroad in red, the temperature becomes higher. Further evidence emerged that this is already visible, the field of radiation has the same origin as that of light. A related site: Dr. Mark Hyman mentions similar findings. In another century, scientists have been received radio waves, which were in the infrared range wavelengths. This is a reasonable assurance of the same nature of radio waves, infrared rays and light. All this – just different kinds of electromagnetic waves.
Without them we would not be able to watch tv, talk on a cell phone listen to the radio. It should be noted that any body, liquid or solid when it is heated to a specific temperature, it begins to radiate in the infrared spectrum. The higher it is, the higher the intensity and the wavelength shorter. If the temperature does not exceed 300 degrees Celsius, the body looks dark, but if you raise the temperature of the body-emitter, it will be dark red, then red, then yellow, and if the temperature is already very high, the body seems white. Incidentally, all warm-blooded animals 'light' in the infrared. This knowledge will be useful if you decide to buy an infrared heater.
