  2. Sinusoidal plane wave - Wikipedia

    en.wikipedia.org/wiki/Sinusoidal_plane_wave

    The same sinusoidal plane wave above can also be expressed in terms of sine instead of cosine using the elementary identity ⁡ = ⁡ (+ /) (,) = ⁡ ((^) + ′) where ′ = + /. Thus the value and meaning of the phase shift depends on whether the wave is defined in terms of sine or co-sine.

  3. Plane wave - Wikipedia

    en.wikipedia.org/wiki/Plane_wave

    The term is also used, even more specifically, to mean a "monochromatic" or sinusoidal plane wave: a travelling plane wave whose profile () is a sinusoidal function. That is, (,) = ⁡ (() +) The parameter , which may be a scalar or a vector, is called the amplitude of the wave; the scalar coefficient is its "spatial frequency"; and the scalar is its "phase shift".

    en.wikipedia.org/wiki/Sinusoidal_plane-wave...

    Sinusoidal plane-wave solutions are particular solutions to the wave equation. The general solution of the electromagnetic wave equation in homogeneous, linear, time-independent media can be written as a linear superposition of plane-waves of different frequencies and polarizations .

  5. Traveling plane wave - Wikipedia

    en.wikipedia.org/wiki/Traveling_plane_wave

    The wavefronts of a traveling plane wave in three-dimensional space. In mathematics and physics , a traveling plane wave [ 1 ] is a special case of plane wave , namely a field whose evolution in time can be described as simple translation of its values at a constant wave speed c {\displaystyle c} , along a fixed direction of propagation n → ...

    Of these, the most important examples are the electromagnetic plane waves, in which the radiation has planar wavefronts moving in a specific direction at the speed of light. Of these, the most basic is the monochromatic plane waves, in which only one frequency component is present. This is precisely the phenomenon that this solution model, but ...
