  2. 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".

  3. Ship motions - Wikipedia

    en.wikipedia.org/wiki/Ship_motions

    The vertical/Z axis, or yaw axis, is an imaginary line running vertically through the ship and through its centre of mass. A yaw motion is a side-to side movement of the bow and stern of the ship. The transverse/Y axis, lateral axis, or pitch axis is an imaginary line running horizontally across the ship and through the centre of mass. A pitch ...

  4. Longitudinal mode - Wikipedia

    en.wikipedia.org/wiki/Longitudinal_mode

    The first six longitudinal modes of a plane-parallel cavity. A longitudinal mode of a resonant cavity is a particular standing wave pattern formed by waves confined in the cavity. The longitudinal modes correspond to the wavelengths of the wave which are reinforced by constructive interference after many reflections from the cavity's reflecting ...

    Position of a point in space, not necessarily a point on the wave profile or any line of propagation d, r: m [L] Wave profile displacement Along propagation direction, distance travelled (path length) by one wave from the source point r 0 to any point in space d (for longitudinal or transverse waves) L, d, r

  6. Polarization (waves) - Wikipedia

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

    Considering a monochromatic plane wave of optical frequency f (light of vacuum wavelength λ has a frequency of f = c/λ where c is the speed of light), let us take the direction of propagation as the z axis. Being a transverse wave the E and H fields must then contain components only in the x and y directions whereas E z = H z = 0.

  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. Longitudinal wave - Wikipedia

    en.wikipedia.org/wiki/Longitudinal_wave

    "Longitudinal waves" and "transverse waves" have been abbreviated by some authors as "L-waves" and "T-waves", respectively, for their own convenience. [1] While these two abbreviations have specific meanings in seismology (L-wave for Love wave [2] or long wave [3]) and electrocardiography (see T wave), some authors chose to use "ℓ-waves" (lowercase 'L') and "t-waves" instead, although they ...

  9. Longitudinal axis - Wikipedia

    en.wikipedia.org/wiki/Longitudinal_axis

    Longitudinal axis may refer to: In anatomy, going from head to tail; see Anatomical terms of location § Axes; In aviation, nose to tail of a plane; see Aircraft principal axes § Longitudinal axis (roll) In geography, an imaginary line passing through the centroid of the cross sections along the long axis of an object
