31. In solids, mechanical waves can take many forms including longitudinal waves, transverse waves and surface waves . 32. The largest amplitude signals are seismic surface waves that reach the antipode after about 100 minutes. 33. Like electromagnetic waves which produce surface plasmons on rough surfaces, phonons can also induce surface waves . 34. Momentum of the surface winds is transferred into the energy flux by the ocean surface waves . 35. This measurement is called the surface wave magnitude. 36. This is because the material can suppress surface wave propagation within the prescribed range of forbidden frequencies. 37. Within microwave field theory, the interface of a dielectric and conductor supports " surface wave transmission ". 38. Surface waves therefore decay more slowly with distance than do body waves, which travel in three dimensions.39. Another tidal wave technology harvests energy from surface waves or from pressure fluctuations below the sea surface. 40. It had an estimated magnitude of 8.1 on the surface wave magnitude scale and triggered a destructive tsunami.
