matter waves
mechanical and electromagnetic waves may often seem to travel through space; but, while they can carry energy, momentum, and information through matter or empty space, they may do that without transferring any mass. in mathematics and electronics waves are studied as signals. on the other hand, some waves do not appear to move at all, like standing waves (which are fundamental to music) and hydraulic jumps. some, like the probability waves of quantum mechanics, may be completely static.

the wave heating theory, proposed in 1949 by evry schatzman, proposes that waves carry energy from the solar interior to the solar chromosphere and corona. the sun is made of plasma rather than ordinary gas, so it supports several types of waves analogous to sound waves in air. the most important types of wave are magneto-acoustic waves and alfvén waves. magneto-acoustic waves are sound waves that have been modified by the presence of a magnetic field, and alfvén waves are similar to ultra low frequency radio waves that have been modified by interaction with matter in the plasma. both types of waves can be launched by the turbulence of granulation and super granulation at the solar photosphere, and both types of waves can carry energy for some distance through the solar atmosphere before turning into shock waves that dissipate their energy as heat.
