11. Colleagues at UC Berkeley were better able to utilize the black body radiation and more accurately measure the temperature. 12. To see this consider a small ball of radius r placed inside the encolsure filled with black body radiation . 13. According to the black body radiation law, all objects with temperature greater than absolute zero emit IR radiation. 14. :: : : IR is related to black body radiation , in that bodies at room tempuarture emit IR radiation. 15. If you simply stop the nuclear reactions, the Sun will still be very hot and still radiating black body radiation . 16. The crucial early experiments that supported the photon hypothesis were the spectrum of black body radiation , and the photoelectric effect. 17. Maybe it's about black body radiation ? Keenan Pepper 03 : 42, 15 February 2008 ( UTC) 18. Now, this is where "'Debye model "'and Planck's law of black body radiation differ. 19. A more-complete derivation of black body radiation would yield a fully continuous and'wave-like'electromagnetic field with no quantization. 20. When Max Planck later formulated the correct black body radiation function it did not include Wien's constant " b " explicitly.
