We review emission processes within the supernova (SN) ejecta. Examplesof the application of the theory to observational data are presented.The emission processes and thermal condition within the SN ejecta changeas a function of time, and multi-epoch observations are important toobtain comprehensive views. Through the analyses, we can constrain theprogenitor radius, compositions as a function of depth, ejectaproperties, explosion asymmetry and so on. Multi-frequency follow-up isalso important, including radio synchrotron emissions and the inverseCompton effect, gamma-ray emissions from radioactive decay of newlysynthesized materials. The optical data are essential to make the bestuse of the multi-frequency data.
