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
Regular sound correspondences between Hungarian and other Uralic languages Regular sound correspondences between Hungarian and other Uralic languages There are numerous regular sound correspondences between Hungarian and the other Uralic languages. For example, Hungarian "á" corresponds to Khanty "o" in certain positions, and Hungarian "h" corresponds to Khanty "x", while Hungarian final "z" corresponds to Khanty final "t". These can be seen in Hungarian "ház" ("house") and Khanty "xot" ("house"), or Hungarian "száz" ("hundred") and Khanty "sot" ("hundred"). Hungarian and Khanty are closely connected, either genealogically or as part of a language area. The distance between Hungarian and the Finnic languages is greater, but the correspondences are also regular.
