WebApr 21, 2024 · Example 2.2. 1. Use Equation to show that the units of ρ (λ,T)dλ are J / m 3 as expected for an energy density. Equation 2.2.2 gives ρ (λ,T)dλ, the radiation density ( J / m 3) between λ and λ + dλ inside the cavity from which the black-body radiation is emitted. The parameters in the equation are Planck’s constant, the speed of ... WebA perfect absorber \black body" is a body with ( ;T) = 1 for all ;T.
