Exam (elaborations) TEST BANK FOR Quantum Physics 3rd Edition By Steph The energy contained in a volume dV is U(ν,T)dV = U(ν,T)r 2 drsinθdθdϕ when the geometry is that shown in the figure. The energy from this source that emerges through a hole of area dA is dE(ν,T) = U(ν,T)dV dAcosθ 4πr 2 The total energy emitted is . dE(ν,T) = dr dθ dϕU(ν,T)sinθ cosθ dA 0 4π 2π ∫ 0 π /2 ∫ 0 cΔt ∫ = dA 4π 2πcΔtU(ν,T) dθ sinθ cosθ 0 π / 2 ∫ = 1 4...
