1. The phenomenon is distinct from that of black body radiation . 2. Does this mean I have to use laws of Black body radiation ? 3. Black body radiation emitted by a human has a peak wavelength of 9343 nm.4. The sensors work on the basis of a theory called " black body radiation ". 5. Which is just the spectral energy density for Planck's law of black body radiation . 6. The gas becomes incandescent and emits a flash of intense visible and ultraviolet black body radiation . 7. Is it due to different temperatures ( ie . black body radiation ) or different chemical reactions? 8. The last papers of Gershun were devoted to black body radiation spectrum density and rough surface light scattering. 9. Other smaller energy losses include black body radiation directly from the hot gasses and chemical reactions between ionized gasses. 10. He derived this law from the measurements of the French physicists Planck's law of black body radiation :
