Reflection and refraction
Acoustics - Propagation in a solid

Since, in an isotropic solid, a compression wave L (longitudinally polarized) and a shear wave T (transversely polarized) can propagate, any wave of vector k ^I originating from an isotropic solid (1) arriving on a surface in rigid contact with an isotropic solid (2) is, in principle, capable of generating :

• two reflected waves (L ₁ , T ₁ ), of vectors k _L1 , and k _T1 in solid (1) ;

• two refracted waves (L ₂ , T ₂ ), of vectors k _L2 and k _...
