- The present study investigated the localization of the. vertex waves. Vertex waves are spike-shaped wave-. forms seen in the EEG leads located in the superior. parietal area during late stage 1 and stage 2 sleep. [1,10]. Vertex waves are thought to have numerous. generators [6] and possibly are secondary evoked po-.

Wave interference A simple form of interference pattern is obtained if two plane waves of the same frequency intersect at an angle. Interference is essentially an energy redistribution process. The energy which is lost at the destructive interference is regained at the constructive interference.

surface wave A seismic wave that travels across the surface of the earth rather than through it. Surface waves usually travel more slowly and have larger amplitudes and longer wavelengths than body waves. An electromagnetic wave that propagates close to the surface of the Earth. See also groundwave and skywave.

Rayleigh wave Rayleigh wave. Rayleigh wave n. A type of seismic surface wave that moves with a rolling motion, causing rock particles to vibrate in directions both perpendicular and parallel to the main direction of wave propagation. Rayleigh waves are slower than Love waves.

Wave equation A solution to the 2D wave equation. The wave equation is an important second-order linear hyperbolic partial differential equation for the description of waves—as they occur in physics—such as sound waves, light waves and water waves. It arises in fields like acoustics, electromagnetics, and fluid dynamics.

Wave motion Wave motion, propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.

wave wave. n. 1. A disturbance traveling through a medium by which energy is transferred from one particle of the medium to another without causing any permanent displacement of the medium itself. 2.

Unit 8-Waves Vocabulary Unit 8-Waves Vocabulary. Antinode: The point on a wave of greatest displacement. Atmospheric Wave: a periodic disturbance in the fields of atmospheric variables (like surface pressure or geopotential height, temperature, or wind velocity) which may either propagate (traveling wave) or not (stationary wave).

Vertex (geometry) For vertices in the geometry of curves, see Vertex (curve). For other uses of the word, see Vertex (disambiguation). In geometry, a vertex (plural: vertices or vertexes) is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices. 1 Definition.

Transverse wave transverse wave. 1  motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.

- The term surface wave can describe waves over an ocean, even when they are approximated by Airy functions and are more properly called creeping waves. Examples are the waves at the surface of water and air (ocean surface waves), or ripples in the sand at the interface with water or air.

Longitudinal waveupdate From Wikipedia, the free encyclopedia. Longitudinal waves, also known as l-waves, are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave.

Waves A wavefront is a line or surface, in the path of a wave motion, where all the displacements at any point have the same phase. A point source leads to circular wavefronts, at large distances from the source they are straight lines. wave is a method of transferring energy from one place to another without transferring matter. Mechanical waves are those that require a medium for their transfer and include water waves, sound waves and waves in stretched strings.

- Gamma waves. A gamma wave is a pattern of neural oscillation in humans with a frequency between 25 and 100 Hz, though 40 Hz is typical. According to a popular theory, gamma waves may be implicated in creating the unity of conscious perception (the binding problem).

Vertex (geometry) A vertex of a plane tiling or tessellation is a point where three or more tiles meet; generally, but not always, the tiles of a tessellation are polygons and the vertices of the tessellation are also vertices of its tiles.

beta waves beta wave. beta wave. The second most common waveform occurring in electroencephalograms of the adult brain, characteristically having a frequency from 13 to 30 cycles per second. It is associated with an alert waking state but can also occur as a sign of anxiety or apprehension. Also called beta rhythm.

Vertex (anatomy) In arthropod and vertebrate anatomy, the vertex (or cranial vertex) refers to the upper surface of the head. In humans, the vertex is formed by four bones of the skull: the frontal bone, the two parietal bones, and the occipital bone.

Standing wave Two opposing waves combine to form a standing wave. In physics, a standing wave – also known as a stationary wave – is a wave in a medium in which each point on the axis of the wave has an associated constant amplitude. The locations at which the amplitude is minimum are called nodes, and the locations where the amplitude is maximum are called antinodes.
