WebA perfect black body is a theoretical. object. It would have these properties: It would have these properties: it would absorb all the radiation that falls on it WebMar 14, 2024 · 4. Cosmic Microwave Background is the most perfect black body that have been observed - it has near ideal Planck spectrum at temperature of 2.7 K. Assuming the theoretical prediction that black holes emit Hawking radiation, it would also be a black body radiation, but it was never observed.
WebFigure 4.05depicts the spectrum of the solar radiation arriving at the top of Earth's atmosphere, from 100 nm to 100,000 nm, and an ideal blackbody radiation curve (smooth curve) for a radiator temperature of 5700K. At the long wavelength end, the Sun's spectrum is very nearly that of the ideal blackbody. WebA perfect black body is a theoretical. object.
