It is not only an important basis for quantum mechanics and photoni cs theory, but also an import ant conclusion of blackbod y radiation, and an im portant foundation of modern measurement. The experimental study of blackbody radiation by computer scanning grating spectrometer and bromine tungsten lamp was carried out.īy means of scrolling grating and sine mechanism, the data were recorded by computer scanning to verify the three laws of blackbody radiation directly, and the radiation, transmission and reception of blackbody were analyzed Error correction.ĭiscover the worlds research 20 million members 135 million publications 700k research projects Join for free Public Full-text 1 Available via license: CC BY-NC 4.0 Content may be subject to copyright. There is already a calibrated bromine tungsten lamp energy curve at 2940k.Īt the beginning of the experiment, we should scan at 2940k color temperature to get the baseline, and then calculate the transfer function.Īgain, the energy curve obtained by scanning at different color temperatures is divided by the transfer function to obtain the correct energy radiation curve. This paper mainly studies and validates the law of blackbody radiation by the WGH-10 blackbody experimental device. 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.īy 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.īlackbody radiation experiment is one of the contents of modern physics experiment in colleges and universities. 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.
