Explain the energy distribution in the spectrum of a black body
Dear Student,
The energy distribution, or spectral energy density, is the energy per unit volume of the cavity that is emitted in the wavelength interval λ to λ + dλ. Note the total area under the curve increases as the temperature increases, indicating that the hotter an object is, the more energy it radiates per unit volume.where T1 > T2 > T3.
Analysis of the data from black body emitters led to the formulation of the Wein displacement law relating the temperature and the wavelength of maximum energy density:
