Longitudinal waveupdate 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.

Matter wave Matter waves are a central part of the theory of quantum mechanics, being an example of wave–particle duality. All matter can exhibit wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave. The concept that matter behaves like a wave is also referred to as the de Broglie hypothesis (/dəˈbrɔɪ/) due to having been proposed by Louis de Broglie in 1924. Matter waves are referred to as de Broglie waves.

- The WKB Approximation. Lectures Nine and Ten The WKB. Approximation. The WKB method is a powerful tool to obtain solutions for many physical problems. It is. generally applicable to problems of wave propagation in which the frequency of the wave is very. high or, equivalently, the wavelength of the wave is very short. The WKB solutions are approximate.

Shock wave Shock wave. In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance. When a wave moves faster than the local speed of sound in a fluid, it is a shock wave. Like an ordinary wave, a shock wave carries energy and can propagate through a medium; however, it is characterized by an abrupt, nearly discontinuous change in pressure, temperature and density of the medium.

- P and S waves. A wave is a vibration that transfers energy from one place to another without transferring matter (solid, liquid or gas). Light and sound both travel in this way. Energy released during an earthquake travels in the form of waves around the Earth. Two types of seismic wave exist, P- and S-waves.

Wave In physics, a wave is an oscillation accompanied by a transfer of energy that travels through space or mass. Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which may or may not displace particles of the medium —that is, with little or no associated mass transport. Waves consist, instead, of oscillations or vibrations (of a physical quantity), around almost fixed locations.

What is a Wave? Definition of a Wave. Webster's dictionary defines a wave as: The most important part of this definition is that a wave is a disturbance or variation which travels through a medium. The medium through which the wave travels may experience some local oscillations as the wave passes, but the particles in the medium do not travel with the wave. The disturbance may take any of a number of shapes, from a finite width pulse to an infinitely long sine wave.

- Thus, the entire K-Wave from peak to peak began in 1815 and ended in 1865, making a total of 50 years. This is the bare minimum for a K-Wave. The next K-Wave began that same year, with commodity prices generally falling into the trough of the deflationary leg of the K-Wave in around 1895 (30 years). From there, they rebounded into the inflationary leg, which lasted until around 1920—25 years.

Bloch wave The light circles represent atoms. A Bloch wave (also called Bloch state or Bloch function or Bloch wave function), named after Swiss physicist Felix Bloch, is a type of wavefunction for a particle in a periodically-repeating environment, most commonly an electron in a crystal.A wavefunction ψ is a Bloch wave if it has the form: Bloch wave (bottom) can be broken up into the product of a periodic function (top) and a plane-wave (center). The left side and right side represent the same Bloch wave broken up in two different ways, involving the wave vector k 1 (left) or k 2 (right). The difference (k 1 − k 2) is a reciprocal lattice vector.

Wave motion transfers energy from one point to another, which may or may not displace particles of the medium —that is, with little or no associated mass transport.Waves consist, instead, of oscillations or vibrations (of a physical quantity), around almost fixed locations. wave can be polarized by the use of a polarizing filter. The polarization of a transverse wave describes the direction of oscillation in the plane perpendicular to the direction of travel. Longitudinal waves such as sound waves do not exhibit polarization.

Signals and Systems/Periodic Signals Half-wave symmetry implies that the second half of the wave is exactly opposite to the first half. A function with half-wave symmetry does not have to be even or odd, as this property requires only that the shifted signal is opposite, and this can occur for any temporal offset.
