Since any electromagnetic radiation, including thermal radiation, conveys momentum as well as energy, thermal radiation also induces very small forces on the radiating or absorbing objects. Normally these forces are negligible, but they must be taken into account when considering spacecraft navigation. Zobacz więcej Thermal radiation is electromagnetic radiation generated by the thermal motion of particles in matter. Thermal radiation is generated when heat from the movement of charges in the material (electrons and protons in … Zobacz więcej There are four main properties that characterize thermal radiation (in the limit of the far field): • Thermal radiation emitted by a body at any temperature consists of a wide range of frequencies. The frequency distribution is given by Zobacz więcej Thermal radiation power of a black body in the orthogonal direction per unit area of radiating surface per unit of solid angle and per unit frequency $${\displaystyle \nu }$$ is given by Planck's law as: or instead of … Zobacz więcej • Siegel, John R.
