  2. Transmission curve - Wikipedia

    en.wikipedia.org/wiki/Transmission_curve

    The transmission curve or transmission characteristic [1] is the mathematical function or graph that describes the transmission fraction of an optical or electronic filter as a function of frequency or wavelength. [2]

  3. Charge density wave - Wikipedia

    en.wikipedia.org/wiki/Charge_density_wave

    The effect is somewhat analogous to the standing wave in a guitar string, which can be viewed as the combination of two interfering, traveling waves moving in opposite directions (see interference (wave propagation)). The CDW in electronic charge is accompanied by a periodic distortion – essentially a superlattice – of the atomic lattice.

  4. Wave - Wikipedia

    en.wikipedia.org/wiki/Wave

    A standing wave, also known as a stationary wave, is a wave whose envelope remains in a constant position. This phenomenon arises as a result of interference between two waves traveling in opposite directions. The sum of two counter-propagating waves (of equal amplitude and frequency) creates a standing wave. Standing waves commonly arise when ...

  5. Wave equation - Wikipedia

    en.wikipedia.org/wiki/Wave_equation

    The wave equation is a second-order linear partial differential equation for the description of waves or standing wave fields such as mechanical waves (e.g. water waves, sound waves and seismic waves) or electromagnetic waves (including light waves). It arises in fields like acoustics, electromagnetism, and fluid dynamics.

    For example, sound moving through wind will have its speed of propagation increased by the speed of the wind if the sound and wind are moving in the same direction. If the sound and wind are moving in opposite directions, the speed of the sound wave will be decreased by the speed of the wind. The viscosity of the medium.
