Plane wave ( in the positive x direction)
Description
In the physics of wave propagation, a plane wave is a constant-frequency wave whose wavefronts (surfaces of constant phase) are infinite parallel planes of constant peak-to-peak amplitude normal to the phase velocity vector. A plane wave travelling in the positive x direction is representing by a cosine function.
