The term “radiation” used in this area of Thermopedia is simply an alternative short name of the electromagnetic radiation (or electromagnetic wave) because we are not going to consider the acoustic radiation or the ionizing radiation emitted by radioactive substances. The visible light is the most evident example of electromagnetic radiation. It is well-known that a color of light is determined by the wavelength of electromagnetic wave: the change of color from red to violet corresponds to decreasing the wavelength from about 0.7 µm to 0.4 µm. A more short-wave radiation is called ultraviolet and we cannot see this radiation. For problems of the so-called thermal radiation, a long-wave radiation (as compared with the visible one) appears to be more important. The infrared radiation is characterized by the wavelengths up to one millimeter but we have an experience in direct sensing only the near-infrared radiation by our skin. A good ...
