www.physics.usu.eduequation can be used to describe, for example, the propagation of sound waves in a fluid. In that case q represents the longitudinal displacement of the fluid as the wave propagates through it. The 3D solutions to Eq. (3) that are analogous to the 1D solutions expressed by Eq. (2) can be written as ()i(k x k y k z t) k k k x y z x y z q+ x, y,z ...
