A small surface of area A 1 = 3 cm 2 emits radiation as a blackbody, and

Question:

A small surface of area A₁ = 3 cm² emits radiation as a blackbody, and part of the radiation emitted by A¹ strikes another small surface of area A₂ = 8 cm² oriented as shown in the figure. If the rate at which radiation emitted by A₁ that strikes A₂ is measured to be 274 × 10^-6 W, determine the intensity of the radiation emitted by A₁, and the temperature of A₁. A = 8 cm d A = 3 cm 0 = 40 0 = 55 r= 75 cm
