Planck's law describes the unique and characteristic spectral distribution for electromagnetic radiation in thermodynamic equilibrium, when there is no net flow of matter or energy. Its physics is most easily understood by considering the radiation in a cavity with rigid opaque walls. Motion of the walls can affect the radiation. If the walls are not opaque, then the thermodynamic equilibrium is not isolated. It is of interest to explain how the thermodynamic equilibrium is attain… WebImage transcription text. EXPERIMENT #7 DETERMINATION OF QUANTUM NUMBERS FROM ATOMIC SPECTRUM INTRODUCTION The origin of quantum numbers stems from a theoretical explanation of the intensity of light, emitted from a heated cavity, as function of its wavelength. This is commonly known as blackbody radiation. 6000 5000 2000 K …
