There is already a calibrated bromine tungsten lamp energy curve at 2940k. This paper mainly studies and validates the law of blackbody radiation by the WGH-10 blackbody experimental device. Blackbody radiation experiment is one of the contents of modern physics experiment in colleges and universities. By the end of the 19th century, it was recognized that both the thermal radiation and the optical radiation were electromagnetic waves, and began to study the distribution of radiant energy in different frequency ranges, especially the study of blackbody radiation in theory and practice.
In the early nineteenth century, the study of thermal radiation was supported by thermodynamics and spectroscopy, and the rapid development of electromagnetism and optics was used. It is not only an important basis for quantum mechanics and photonics theory, but also an important conclusion of blackbody radiation, and an important foundation of modern measurement. P>Blackbody radiation theory is one of the important origins of light quantum theory in the twentieth century.
