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 … WebKirchhoff’s Law states that a body that radiates strongly at some wavelength also absorbs radiation strongly at the same wavelength. Therefore an ideal blackbody radiator is both a perfect absorber and …

WebPlanck's Equation and Black Body Radiation. A black body is an object that absorbs light of all frequencies, and if heated, a black body will emit light of a characteristic spectrum. It could be experimentally observed that both the frequency (color) and the intensity (amount) of the light emitted by a black body is a function of its ... WebWien's approximation (also sometimes called Wien's law or the Wien distribution law) is a law of physics used to describe the spectrum of thermal radiation (frequently called the blackbody function). This law was first derived by Wilhelm Wien in 1896.
