The physical property whose change determines reflection coefficients (q.v.) at normal incidence, that is, seismic P-wave velocity multiplied by density. Because reflection coefficients change with angle, the term elastic impedance is sometimes used when referring to nonnormal incidence situations but an equation for elastic impedance is hardly ever used.
