Peak of Blackbody Radiation To find the peak of the radiation curve as indicated in Wien's displacement law, it is necessary to take the derivative of the Planck radiation formula with respect to wavelength. Setting this derivative equal to zero to determine the maximum gives the equation Show This is a trancendental equation which must be solved numerically. It gives the result: Calculation	Index Blackbody radiation concepts
