BLACK BODY RADIATION PACKAGE TUTORIAL
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 total power radiated by a black body at a temperature of 5000 K.
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.
BlackBodyProfile [ temp 1 , temp 2 , … ] 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.
Note that takes the same options as BlackBodyProfile in order to specify different styles for each profile curve. Plot
