The relation which exists between noncommutativity and geometry is used to study the properties of the high-frequency waves on the flat background.This is a contribution to the Proc. of the Seventh International Conference ''Symmetry in Nonlinear Mathematical Physics'' (June 24-30, 2007, Kyiv, Ukraine), published in SIGMA (Symmetry, Integrability and Geometry: Methods and Applications) at http://www.emis.de/journals/SIGMA/High Energy Physics - TheoryWKB Approximation in Noncommutative Gravitytext
