Unformatted text preview: λ is emitted in all directions from a surface per unit d λ per unit surface area. Irradiation: radiation incident from all directions Radiosity: accounts for all radiant energy leaving a surface, reflected and emitted. Besides definitions, what’s really important is how to find q. So, if a small surface area (10-4 m 2 ) emits diffusely with total hemispherical emissive power of 5 X 10 4 W/m 2 to area of 5 X 10-4 m 2 , what is rate of emission intercepted by A 2 and the irradiation G 2 on A 2 ?...
