WebBlack-body radiators are used as broad band radiation sources in IR spectrometers. The only adjustable parameter of the source is the temperature; the higher the temperature, … WebAll matter at a temperature above absolute zero radiates energy. The higher the temperature, the more energy is radiated. For a blackbody, according to the Stefan-Boltzman Law, the amount of energy emitted is proportional to the product of a constant—the Stefan-Boltzman constant, s, which has the value 5.67 x 10-8 Watts m-2 … WebWien's Displacement Law When the temperature of a blackbody radiator increases, the overall radiated energy increases and the peak of the radiation curve moves to shorter wavelengths. When the maximum is evaluated from the Planck radiation formula, the product of the peak wavelength and the temperature is found to be a constant. organisational culture nhs scotland
