A light wave is an example of a transverse wave. The light wave is however composite, all parts of which have transversal wave properties.

A transverse wave is a wave that causes vibration in the medium in a perpendicular direction to its own motion. For example: if a wave moves along the x-axis, its disturbances are in the yz-plane. In other words, it causes medium disturbances across the two-dimensional plane that it is travelling in. Contrary to popular belief, transversal waves do not necessarily move up and down.

Properties

The properties of transverse waves are exemplified by ripples in water, the vibrations of a stretched string or also in electromagnetic waves. In a transverse wave, the molecules of the medium oscillate perpendicular to the direction of propagation. In seismology transverse waves are called secondary, or s waves because they arrive later than the primary, or p waves from an earthquake. The absence of transverse waves traveling through the earth’s core shows that it is liquid. Impact from a water drop causes an upward rebound jet surrounded by circular capillary waves. ... Electromagnetic radiation or EM radiation is a combination (cross product) of oscillating electric and magnetic fields perpendicular to each other, moving through space as a wave, effectively transporting energy and momentum. ...

Examples

Light is composed of transverse waves. See electromagnetic spectrum for information on different types of electromagnetic waves. Electromagnetic waves are transverse waves. A transverse wave could be represented by moving a slinky, spread across a table, to the left and right or up and down. The oscillating string is another example of a transverse wave. in a transverse wave Legend γ = Gamma rays HX = Hard X-rays SX = Soft X-Rays EUV = Extreme ultraviolet NUV = Near ultraviolet Visible light NIR = Near infrared MIR = Moderate infrared FIR = Far infrared Radio waves EHF = Extremely high frequency (Microwaves) SHF = Super high frequency (Microwaves) UHF = Ultra high frequency VHF = Very high frequency HF = High...

Mathematical description

In mathematics, transverse waves are associated with the curl operator and are governed by a vector wave equation, in contrast to longitudinal waves, which are associated with the div operator and are governed by a scalar wave equation. A longitudinal wave exists as compressions moving through the plane in which it is travelling. Energy from this wave is transmitted as mechanical energy. An example would be a slinky which was pushed forward and backwards, compressing and extending it as the motion of the wave was transmitted. The speed of a transverse wave is determined by the equation "wave speed= frequency x wavelength" For other uses, see Curl (disambiguation). ... The wave equation is an important partial differential equation that describes the propagation of a variety of waves, such as sound waves, light waves and water waves. ... In vector calculus, the divergence is an operator that measures a vector fields tendency to originate from or converge upon a given point. ...

A transverse wave is a wave that oscillates perpendicular to the direction it advances.
Transverse waves travel slower than longitudinal waves (which include sound, ripples in water, and certain types of waves from earthquakes, where the particle motion is in the direction of travel), and (except in the case of electromagnetic waves) propagate only in solids, not in liquids or gases.
In mathematics, transverse waves are associated with the curl operator and are governed by a vector wave equation, in contrast to longitudinal waves, which are associated with the div operator and are governed by a scalar wave equation.
Longitudinal wave - Wikipedia, the free encyclopedia (852 words)
For sound waves, the amplitude of the wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave.
Maxwell's equations lead to the prediction of electromagnetic waves in a vacuum, which are transverse (in that the electric fields and magnetic fields vary perpendicularly to the direction of propagation).
Surface wave : waves that is guided along the interface between two different media for a mechanical wave or by a refractive index gradient for an electromagnetic wave.
