Spectral Distribution of Total Energy Emitted by a Black Body versus Temperature
This Demonstration plots the monochromatic emissive power of a black body in at user-set values of the temperature (blue curve). The locus of the maximum values of the monochromatic emissive power (red curve) is given by Wien's displacement law:[more]
The Demonstration also displays the value of as well as the total emissive power, (expressed in ), which is given by the Stefan–Boltzmann law:
