In addition to the basic Stefan's law for
, the total radiated power, Eq. (1), the more
detailed results of this experiment are the curves for 
.
These curves have the interesting property that they can all be
rescaled to fall on top of each other. The most general expression of
Wien's Displacement Law is that
where 
is some universal function independant of
frequency and temperature.
This form indicates that if we were to define new ``scaled'' variables,
then simply, 
, so that if we were to plot all of our data
from different temperatures and frequencies on a plot with these
``scaled'' variables, all of the data would fall on the same
curve, as in the figure below.
