Entropy of blackbody radiation

WebThe characteristics of blackbody radiation can be described in terms of several laws: 1. Planck’s Law of blackbody radiation, a formula to determine the spectral energy density of the emission at each wavelength (E λ) at a particular absolute temperature (T).. 2. Wien’s Displacement Law, which states that the frequency of the peak of the emission (f max) … WebThe sun is a sphere with a radius of 6.96 × 1 0 8 6.96 \times 10^{8} 6.96 × 1 0 8 m and an average surface temperature of 5800 K. Determine the amount by which the sun's thermal radiation increases the entropy of the entire universe each second. Assume that the sun is a perfect blackbody, and that the average temperature of the rest of the universe is 2.73 K.
