Nils Kaufmann,Andre Magner,Nils Neuber as the change of ., or . of a wave as a result of spatial or temporal nonuniformities of the medium. The inhomogeneities arise because of variations in compressibility or acoustic impedance differences. In this section, we almost exclusively treat scattering as a phenomenon of redirection of energy
