Question:

The blackbody energy density given in Equation 2.75 is the energy density per unit frequency interval. In other words, du = ρ(ν)dν is the energy per unit volume between ν and ν + dν. Convert the frequency-dependent ρ(ν) to a wavelength-dependent function ρ(λ) such that du = ρ(ν)dν = ρ(λ)dλ.
