Optical properties of materials - 4gpm

Part II.1 of the course: black body radiation. Introduction and position of the problem. Density of optical modes. Average energy of a mode of frequency ν given by classical physics or by quantum physics. Conversion from energy density in radiation to spectral emittance of the blackbody surface; notions of emissivity and absorptivity. Application: passive radiative cooling of a surface.
