Black-Body Radiation Package
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.
| PeakWavelength[temp] | wavelength of the maximum emission of a black body at the specified temperature |
| TotalPower[temp] | total power of a black body at the specified temperature |
| MaxPower[temp,band] | power of a black body at the specified temperature for the specified wavelength band about the peak wavelength |
Black‐body radiation properties.
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.
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.
about the peak wavelength of a black body at a temperature of 5000 K. | BlackBodyProfile[temp1,temp2,…] | plot the black‐body spectral distribution profiles at the specified temperatures |
This gives the spectral distribution of radiation from a black body for three different temperatures.
Note that BlackBodyProfile takes the same options as Plot in order to specify different styles for each profile curve.
