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
.
