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. WebThe first law of blackbody radiation states that the total energy emitted by a blackbody is proportional to the fourth power of its temperature. This means that the hotter an object is, the more energy it will emit. ... This is because the Sun is much hotter than the Earth, and so its peak emission is shifted toward shorter wavelengths. The ...
