Surface waves in water showing water ripples In mathematics and physical science, a wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities. Periodic …

Transverse waves are contrasted with longitudinal waves, where the oscillations occur in the direction of the wave. The standard example of a longitudinal wave is a sound wave or …

Longitudinal waves are waves which oscillate in the direction which is parallel to the direction in which the wave travels and displacement of the medium is in the same (or opposite) direction …

A sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine function. In mechanics, as a linear motion over time, this is …

In physics, electromagnetic radiation (EMR) or electromagnetic wave (EMW) is a self-propagating wave of the electromagnetic field that carries momentum and radiant energy through space. …

A diagram of the electromagnetic spectrum, showing various properties across the range of frequencies and wavelengths The electromagnetic spectrum is the full range of …

Vector describing a wave; often its propagation directionIn physics, a wave vector (or wavevector) is a vector used in describing a wave, with a typical unit being cycle per metre. It has a …
