Radiative Properties of Surfaces

This lecture covers the relations between surface radiative properties, including spectral and directional properties, total hemispherical properties, and predictions from electromagnetic wave theory. It discusses ideal diffuse selective surfaces, predictions from Fresnel's equations, and Snell's law for non-absorbing media. The lecture also explores view factors for diffuse surfaces, radiative exchange between black and gray diffuse surfaces, and the algebraic evaluation of view factors for complex configurations.
