Descriptif

An important part of Geophysics concerns the imaging of the Earth with waves. This lecture aims at providing students with a solid background of the mechanisms of wave propagation and scattering. The main concepts of wave physics are introduced from a theoretical point of view and are illustrated with various exercices and lab works.
