Heat transmission by radiation

 Radiation is a form of energy known to people in some of its manifestations - light and heat - since early times. People perceived solar light and heat using their inborn senses. Nowadays it is clear that radiation is much more than light and heat, and its effects depend solely on the type of radiation in use. Radiation can propagate itself through space without the need of a material support in the tradition sense, and in vacuum conditions it travels at 300,000 km/sec, no matter the type (thermal, light, cosmic radiation); furthermore, speed is not influenced (qualitatively or quantitatively) by the temperature of the environment.

 Thermal radiation can be transmitted on any distance with no material support, it depends on the temperature of the emitting body, but not on the temperature of the environment.
 
 In the case of traditional, convection heating, heat is transmitted by step-by-step molecular movement (with speeds low below the speed of light in a vacuum - 300,000 km/h), whereas thermal radiation uses the same principle only during the emission and reception stages, throughout the transmission stage it changes into an electromagnetic type of transport. In order to explain the transformation of thermal radiation into electromagnetic infrared radiation (at the emitter) and back into thermal one (at the receiver), M. Planck introduced the term "quantum of energy", an intermittent, pulsating emission of energy carried by a material corpuscle, which L. de Broglie believed had vibrating features. Thus, the quantum of energy, with its corpuscular and energetic parts would be two instances of the same physical reality (a corpuscle is the basic element of the matter, the same for any object or substance). Otherwise said, radiation is part of the energy of an atom carried by a basic element of the matter. Therefore, radiation implies loss of energy, just like the Sun loses 4,000,000 metric tons of its mass every second (the equivalent of the energy it radiates in outer space).
 
 According to its wavelength, radiant energy falls into several classes: - under 0,05 µµ - cosmic radiation; 0,5 µµ to 10 µµ - gamma radiation; 10 µµ to 20 µm -  Roentgen/X-rays; 20 µm to 0,38 µ - UV radiation; 0,38 µ to 0,72 µ - light (radiation);0,72 µ to 0,8 mm - thermal radiation or ultra-red radiation (short wave radiations in this class are the infrared radiations); 0,2 mm to x km - electric radiations.

 Single-wavelength radiations are called monochromatic. Wavelength changes when passing from one medium to another, while radiation frequency remains the same, therefore the speed of propagation depends on the environment.
