WebAccording to Zettili, we can derive Wien's displacement law from Planck's energy density u ~ ( λ, T) = 8 π h c λ 5 1 e h c / k T λ − 1 where λ is the wavelength and T is the … 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 ).
