Question 1: For a small surface of area Az = 10-3m2 is known to emit diffusely, and from measurements the total intensity associated with emission in the normal direction is n = w 7000 sr. Radiation emitted from the surface is intercepted by three other surfaces of area A1 Az = Az = A. = 10-3m², which 0.5 m from A, and oriented as shown in the figure below. m2 A A2 0.5 m (А. 0.5 m 60°-45° 0.5 m For this configuration calculate (i) The intensity associated with emission in each of the three directions (10) The solid angles subtended by the three surfaces when viewed from A (III) The rate at which radiation emitted by Ayis intercepted by the three surfaces? (iv) The irradiation at surfaces Az. Ag and A, due to A,
