Example of a blackbody
WebDec 8, 2014 · 12. Black body radiation was one of the first indications that electromagnetic energy is quantized. As the temperature decreases, the peak of the black-body radiation curve moves to lower intensities and longer wavelengths. The black-body radiation graph is also compared with the classical model of Rayleigh and Jeans. A realization of a black body refers to a real world, physical embodiment. Here are a few. In 1898, Otto Lummer and Ferdinand Kurlbaum published an account of their cavity radiation source. Their design has been used largely unchanged for radiation measurements to the present day. It was a hole in the wall of a platin…
