BLACK BODY RADIATION 程序包 教程
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.
| 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]= |  |
| BlackBodyProfile[temp1,temp2,...] | plot the black-body spectral distribution profiles at the specified temperatures |
Plotting black-body profiles.
This gives the spectral distribution of radiation from a black body for three different temperatures.
| Out[5]= |  |
Note that BlackBodyProfile takes the same options as Plot in order to specify different styles for each profile curve.
