Wave shoaling and the angular frequency is proportional to its local rate of change, Simplifying to one dimension and cross-differentiating it is now easily seen that the above definitions indicate simply that the rate of change of wavenumber is balanced by the convergence of the frequency along a ray; Assuming stationary conditions (formula_27), this implies that wave crests are conserved and the frequency must remain constant along a wave ray as formula_28. As waves enter shallower waters, the decrease in group velocity caused by the reduction in water depth leads to a reduction in wave length formula_29 because the nondispersive shallow water
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.
