  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".

  4. Maxwell's equations - Wikipedia

    en.wikipedia.org/wiki/Maxwell's_equations

    A sinusoidal plane wave is one special solution of these equations. Maxwell's equations explain how these waves can physically propagate through space. The changing magnetic field creates a changing electric field through Faraday's law.

    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. 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.

  7. Sine wave - Wikipedia

    en.wikipedia.org/wiki/Sine_wave

    A sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine function. In mechanics , as a linear motion over time, this is simple harmonic motion ; as rotation , it corresponds to uniform circular motion .

    Bill Clinton is one proud grandpa!. On Monday, Nov. 25, the former President of the United States, 78, appeared on an episode of Live with Kelly and Mark and spoke about how he and the former ...

  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 ...
