Document Summary

Solution to the wave equation (x, ) t) t = f v. Wave equation derived from newton"s 2nd law. A general solution to the wave equation y (x, ) t = f v t) As long as speed is constant, any wave will satisfy the wave equation (x. Speed of a wave determined by the medium. Speed of the wave is determined by the medium and not by how the wave was initially excited. Observations y t = f 1 v + f 2 + v t) (x (x t) The sum of the waves appear to stand still (ex. The waves look the same before and after (ex. Wavelength is the same as the incoming waves. There are nodes (points of constant zero displacement) Displacement of overlap (wave 1 + wave 2) cos[k(x cos[k(x t = a t = a. + v t)] t)] y y t = a.
