Electromagnetic radiation emitted by electrons in a thermal gas.
Electromagnetic radiation emitted (in two pulses from an air burst) from the fireball as a consequence of its very high temperature; it consists essentially of ultraviolet, visible, and infrared radiations. In the early stages (first pulse of an air burst), when the temperature of the fireball is very high, the ultraviolet predominates; in the second pulse, the temperatures are lower and most of it is in the visible and infrared regions of the spectrum.
radiation produced by a body because it is hotter than its surroundings. In producing radiation, the body reduces its thermal energy.
electromagnetic radiation (infrared, visible, and ultraviolet) emitted from the fireball of a nuclear explosion as a consequence of high temperatures
Electromagnetic energy with wavelengths of 5 to 80 microns. Thermal radiation is of longer wavelengths than near infrared radiation and is emitted by terrestrial objects like trees, human beings, heated buildings, or power plants. See Also: electromagnetic energy, micron, infrared radiation
Electromagnetic radiation emitted by all matter in thermal equilibrium as the result of the thermal excitation of its molecules.
radiation of or relating to, or caused by heat.
Radiant Heat that can't be seen, this is what is used in radiant panel heating.
Electromagnetic radiation emitted by a warm body.
electromagnetic radiation emitted from a heat or light source as a consequence of its temperature; it consists essentially of ultraviolet, visible, and infrared radiation.
Radiation released by virtue of an object's heat; namely, by charged particles interacting with other charged particles.
Energy transfer in the form of electromagnetic waves from a body by virtue of its temperature, including infrared radiation, ultraviolet radiation, and visible light.
The radiation emitted by any body or gas that is not at absolute zero.
The energy radiated and emitted by hot surfaces through electro-magnetic waves.
Electromagnetic radiation due to the fact that a body is hot; often characterized by a blackbody spectrum.
ElectromÃ¡gnetica radiation emitted by electrons in a thermal gas.
Electromagnetic energy whose natural wavelength fall between .7 and 100 microns.
electromagnetic radiation emanating from any object not at absolute zero
Radiation released by virtue of an object's heat, namely, the transfer of heat energy into the radiative energy of electromagnetic waves. Examples of thermal radiation are sunlight, the orange glow of an electric range, and the light from in incandescent light bulb.
Thermal radiation is electromagnetic radiation emitted from the surface of an object which is due to the object's temperature. Infrared radiation from a common household radiator or electric heater is an example of thermal radiation, as is the light emitted by a glowing incandescent light bulb. Thermal radiation is generated when heat from the movement of charged particles within atoms is converted to electromagnetic radiation.The emitted wave frequency of the thermal radiation is a probability distribution depending only on temperature, and for a genuine black body is given by Planckâ€™s law of radiation.
