Problem 2: A small surface A1, with area 7 cm2, emits radiation as a blackbody at 800K. Part of its radiation hits anot...
2. A small surface of area A measurements the total intensity associated with emission in the normal direction is In 103 m2 is known to emit diffusely, and from 7000 W/m2-s. Radiation emitted from the surface is intercepted by two other surfaces of area A2 A3 = 103 m2, which are oriented as shown. What is intensity associated with emission in each of the two directions? What are the solid angles subtended by the three surfaces when viewed from Ai?...
A small circular surface of area A 2cm located at the center of a 2-m-diameter sphere emits radiation as a blackbody at T 1000 K. Determine the rate at which radiation energy is streaming through a D-1-cm-diameter hole located (a) on top of the sphere directly above Ai and (b) on the side of sphere such that the line that connects the centers of A: and Az makes 45" with surface A A small circular surface of area A 2cm...
