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 500° has a hole with area 5.00 mm². Part A How long does it take for the cavity to radiate 200 J of energy through the hole? Express your answer in seconds. ΜΕ ΑΣΦ ?
