<p>the case of non-normal incidence, due to mode conversion between <a href="page.php?w=P-waves">P-waves</a> and <a href="page.php?w=S-waves">S-waves</a>, and is described by the <a href="page.php?w=Zoeppritz_equations">Zoeppritz equations</a>.  In 1919, Karl Zoeppritz derived 4 equations that determine the amplitudes of <a href="page.php?w=Reflection_%28physics%29">reflected</a> and <a href="page.php?w=refraction">refracted</a> waves at a planar interface for an incident P-wave as a function of the angle of incidence and six independent elastic</p><p>
