Wave amplitude formula_4 described by the equation: where The units of the amplitude depend on the type of wave. Transverse mechanical waves (e.g., a wave on a string) have an amplitude expressed as a distance (e.g., meters), longitudinal mechanical waves (e.g., sound waves) use units of pressure (e.g., pascals), and electromagnetic waves (a form of transverse vacuum wave) express the amplitude in terms of its electric field (e.g., volts/meter). The wavelength formula_30 is the distance between two sequential crests or troughs (or other equivalent points), generally is measured in meters. A wavenumber formula_17, the spatial frequency of the wave in radians
The Wave 96.4 FM The Wave 96.4 FM 96.4 The Wave is a British Independent Local Radio station that serves the Swansea Bay area of West Wales. The station is owned by Wireless Group and mainly broadcasts chart and contemporary music, alongside news and local information, for an audience of under 40s. Initially broadcasting as 95.1 Swansea Sound on 30 September 1974, the station split into two separate services on 30 September 1995, creating a new music-led station called 96.4 Sound Wave when it moved its frequency from 95.1 FM to 96.4 FM, while Swansea Sound continued to broadcast on 1170 AM.
