WebSep 15, 2024 · The spectrum is generally divided into seven regions in order of decreasing wavelength and increasing energy and frequency. The common designations are radio waves, microwaves, infrared (IR),... WebApr 30, 2024 · Surface (or ground) waves are located very near the earth’s surface. Space waves occur in the lower atmosphere (troposphere). Sky waves occur in the upper atmosphere (ionosphere). The boundaries between these regions are somewhat fuzzy. In many cases, it is not possible to examine surface waves without considering space waves. In physics, a surface wave is a mechanical wave that propagates along the interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Gravity waves can also occur within liquids, at the interface between two fluids with different densities. Elastic … See more In seismology, several types of surface waves are encountered. Surface waves, in this mechanical sense, are commonly known as either Love waves (L waves) or Rayleigh waves. A seismic wave is a wave that travels through … See more Ground waves are radio waves propagating parallel to and adjacent to the surface of the Earth, following the curvature of the Earth. … See more Standards and doctrines • "Surface wave Archived 2024-09-03 at the Wayback Machine".
