Unformatted text preview: 1128C Irradiation G is the radiation flux incident on a surface from all directions. For diffusely incident radiation, irradiation on a surface is related to the intensity of incident radiation by i I G = (or i I G , = for spectral quantities). 1129C Radiosity J is the rate at which radiation energy leaves a unit area of a surface by emission and reflection in all directions. . For a diffusely emitting and reflecting surface, radiosity is related to the intensity of emitted and reflected radiation by r e I J + = (or r e I J + = , for spectral quantities). 1130C When the variation of a spectral radiation quantity with wavelength is known, the correcponding total quantity is determined by integrating that quantity with respect to wavelength from λ = 0 to λ = ∞ . 1111...
