Miscellaneous`BlackBodyRadiation`A body that absorbs all radiation incident on it is called an ideal black body. This package provides functions giving the basic properties of black-body radiation at a specified temperature, and a function for plotting black-body spectral distributions. Black-body radiation properties. This loads the package. The surface of the sun is about 5000 K. Assuming the sun is a black-body radiator, this gives the wavelength at which its spectrum peaks.
Out[2]= |  |
This gives the total power radiated by a black body at a temperature of 5000 K.
Out[3]= |  |
This gives the radiative power in the wavelength interval of 0.1  about the peak wavelength of a black body at a temperature of 5000 K.
Out[4]= |  |
Plotting black-body profiles. This gives the spectral distribution of radiation from a black body for three different temperatures.
Out[5]= |  |
Note that you can use the option PlotStyle -> { ,  , ... } with BlackBodyProfile to specify different styles for each profile curve.
