The wave modes derived using MHD plasma theory are called magnetohydrodynamic waves or MHD waves. In general there are three MHD wave modes: • Pure (or oblique) Alfvén wave • Slow MHD wave WebbIn an MHD flow, however, there are three characteristic velocities: the sound speed, and also v F and v S,thespeeds of the fast and slow MHD waves. Shocks are associated …
