Abstract

The properties of EM radiation can be considered into two main groups: wave nature and particle nature. The particle nature (or quantum nature) of light is used to explain the phenomena of selective absorption and emission. Important blackbody radiation principles include the Wien’s Displacement Law, Stefan-Boltzmann Law, Rayleigh-Jean’s Law, Kirchoff’s Law, and finally the most important the Planck’s Law. EM radiation has a wide spectrum ranging from gamma rays to radiowaves. Atmosphere and ground materials exhibit different types of interaction with EM radiation of different wavelengths.
