attenuation The falling off of the energy density of radiation with distance from the source, or with passage through an absorbing or scattering medium.optics   
inverse bremsstrahlung Absorption of a photon by an electron in the field of a nucleus.atomic physicsworld pointbremsstrahlung 
selective absorption The process by which light from an astronomical object grows red as the light travels through interstellar dust. Dust scatters blue light more than red, thus leaving predominantly red light transmitted.opticsreddening
