  2. Sawtooth wave - Wikipedia

    en.wikipedia.org/wiki/Sawtooth_wave

    The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform. It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle. A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform. The convention is that a sawtooth wave ramps upward and then sharply drops.

    Wave properties may refer to: Physical properties of waves : transmission, reflection, polarization, diffraction, refraction and others Mathematical description of waves : amplitude, frequency, wavelength, and others

  4. Square wave - Wikipedia

    en.wikipedia.org/wiki/Square_wave

    In an ideal square wave, the transitions between minimum and maximum are instantaneous. The square wave is a special case of a pulse wave which allows arbitrary durations at minimum and maximum amplitudes. The ratio of the high period to the total period of a pulse wave is called the duty cycle. A true square wave has a 50% duty cycle (equal ...

  5. Electromagnetic radiation - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation

    Electromagnetic waves in free space must be solutions of Maxwell's electromagnetic wave equation. Two main classes of solutions are known, namely plane waves and spherical waves. The plane waves may be viewed as the limiting case of spherical waves at a very large (ideally infinite) distance from the source.

  6. Wave - Wikipedia

    en.wikipedia.org/wiki/Wave

    A standing wave, also known as a stationary wave, is a wave whose envelope remains in a constant position. This phenomenon arises as a result of interference between two waves traveling in opposite directions. The sum of two counter-propagating waves (of equal amplitude and frequency) creates a standing wave. Standing waves commonly arise when ...

  7. Wave equation - Wikipedia

    en.wikipedia.org/wiki/Wave_equation

    By comparison with vector wave equations, the scalar wave equation can be seen as a special case of the vector wave equations; in the Cartesian coordinate system, the scalar wave equation is the equation to be satisfied by each component (for each coordinate axis, such as the x component for the x axis) of a vector wave without sources of waves ...

  8. Wave packet - Wikipedia

    en.wikipedia.org/wiki/Wave_packet

    The narrow-width limit of the Gaussian wave packet solution discussed is the free propagator kernel K. For other differential equations, this is usually called the Green's function, [22] but in quantum mechanics it is traditional to reserve the name Green's function for the time Fourier transform of K.

  9. 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".
