An Ideal Blackbody. A large cavity that has a very small
Chapter 39, Problem 39.6(choose chapter or problem)
An Ideal Blackbody. A large cavity that has a very small hole and is maintained at a temperature T is a good approximation to an ideal radiator or blackbody. Radiation can pass into or out of the cavity only through the hole. The cavity is a perfect absorber, since any radiation incident on the hole becomes trapped inside the cavity. Such a cavity at \(400^\circ \mathrm{C}\) has a hole with area \(4.00 \ \mathrm{mm}^2\) . How long does it take for the cavity to radiate 100 J of energy through the hole?
