WebWien’s Displacement Law The second phenomenological observation from experiment was Wien’s Displacement Law. Wien's law identifies the dominant (peak) wavelength, or color, of light coming from a body at a given temperature. As the oven temperature varies, so does the frequency at which the emitted radiation is most intense (Figure 1.1.3 ). WebWien’s Displacement Law Differentiating Planck’s function and setting the derivative equal to zero yields the wavelength of peak emission for a blackbody at temperature T λm ≈ 2900 T where λm is expressed in microns and T in degrees kelvin.
