In Wilhelm Wien derived a formula for blackbody radiation using thermodynamic arguments that for a time was believed to be correct. His formula, the Wien distribution law, is
exp
a Starting with eq find the expression for Hint: You will have to substitute both for and for
b Using your answer to part a find an expression for the total intensity of light predicted to be emitted by a blackbody according to Wien's distribution law.
Does your result agree with the StefanBoltzmann expression : If so find the value predicted for in units of recalling that watt Note: In principle we could find by integrating eq but in practice it is easier to do the integration over rather than over
