Wave Vector

The
For a wave propagation in a direction described by the spherical coordinates ,
the wavevector
The x-component of the wavevector, , determines the rate of change of the phase of a propagating plane wave in the +x-direction. The same definitions apply for the y- and z-directions. The wave vector is a property of plane waves. The phase variation for a plane wave will always be . Hence, the magnitude of the wave vector will be equal to the wavenumber. Therefore:
If =, then the other two components of the wave vector (ky and kz) must be zero.
