  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. Sine wave - Wikipedia

    en.wikipedia.org/wiki/Sine_wave

    Tracing the y component of a circle while going around the circle results in a sine wave (red). Tracing the x component results in a cosine wave (blue). Both waves are sinusoids of the same frequency but different phases. A sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine ...

  4. 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 .

  6. Monochromatic electromagnetic plane wave - Wikipedia

    en.wikipedia.org/wiki/Monochromatic...

    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 ...

  7. Wave - Wikipedia

    en.wikipedia.org/wiki/Wave

    A plane wave is an important mathematical idealization where the disturbance is identical along any (infinite) plane normal to a specific direction of travel. Mathematically, the simplest wave is a sinusoidal plane wave in which at any point the field experiences simple harmonic motion at one frequency.

  9. Envelope (waves) - Wikipedia

    en.wikipedia.org/wiki/Envelope_(waves)

    In physics and engineering, the envelope of an oscillating signal is a smooth curve outlining its extremes. [1] The envelope thus generalizes the concept of a constant amplitude into an instantaneous amplitude. The figure illustrates a modulated sine wave varying between an upper envelope and a lower envelope. The envelope function may be a ...
