A diffuse small surface, A1, has an area of 10⁻⁴ m² and emissive power of E1 = 5 x 10⁴ W/m². A second surface, A2, intercepts the emissive power from A1. The area of A2 is 5 x 10⁻⁴m² and is located 0.5 m from surface A1. The angle, 1, is 60o and the angle, 2, is 30o. Both angles represent the angular displacement from a normal vector and the vectorrepresenting the distance between the center of the two surfaces.a. Determine the emissive power [W] intercepted by a surface, A2. b. Calculate the irradiation, G2 [W/m²], on A2 from A1.
