21. Another application is as stop band device for surface wave propagation along the interface. 22. In addition to this there is a surface wave . 23. In 1947, the Dutch astronomer Hendrik van de Hulst suggested that surface waves are involved. 24. These surface waves are called " action waves ". 25. It is for this reason that internal waves move in slow-motion relative to surface waves . 26. The phases of an ocean surface wave : 1. 27. Like electromagnetic waves which produce surface plasmons on rough surfaces, phonons can also induce surface waves . 28. The largest amplitude signals are seismic surface waves that reach the antipode after about 100 minutes. 29. This measurement is called the surface wave magnitude. 30. Momentum of the surface winds is transferred into the energy flux by the ocean surface waves .
