  2. Geometric terms of location - Wikipedia

    en.wikipedia.org/wiki/Geometric_terms_of_location

    Transverse – intersecting at any angle, i.e. not parallel. Orthogonal (or perpendicular) – at a right angle (at the point of intersection). Elevation – along a curve from a point on the horizon to the zenith, directly overhead. Depression – along a curve from a point on the horizon to the nadir, directly below.

  3. Perpendicular - Wikipedia

    en.wikipedia.org/wiki/Perpendicular

    The transverse axis of a hyperbola is perpendicular to the conjugate axis and to each directrix. The product of the perpendicular distances from a point P on a hyperbola or on its conjugate hyperbola to the asymptotes is a constant independent of the location of P. A rectangular hyperbola has asymptotes that are perpendicular to each other.

  4. Transverse wave - Wikipedia

    en.wikipedia.org/wiki/Transverse_wave

    For any plane perpendicular to the ray, each field has always the same value at all points of the plane. Propagation of a transverse spherical wave in a 2d grid (empirical model) In physics , a transverse wave is a wave that oscillates perpendicularly to the direction of the wave's advance.

  5. Polarization (waves) - Wikipedia

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

    Electromagnetic waves (such as light), traveling in free space or another homogeneous isotropic non-attenuating medium, are properly described as transverse waves, meaning that a plane wave's electric field vector E and magnetic field H are each in some direction perpendicular to (or "transverse" to) the direction of wave propagation; E and H ...

  6. Transversal (geometry) - Wikipedia

    en.wikipedia.org/wiki/Transversal_(geometry)

    A transversal that cuts two parallel lines at right angles is called a perpendicular transversal. In this case, all 8 angles are right angles [1] When the lines are parallel, a case that is often considered, a transversal produces several congruent supplementary angles. Some of these angle pairs have specific names and are discussed below ...

  7. Anatomical terms of location - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_location

    The horizontal plane, also known as the transverse plane, which is perpendicular to the other two planes. [2] In a human, this plane is parallel to the ground; in a quadruped, this divides the animal into anterior and posterior sections.

  8. List of equations in wave theory - Wikipedia

    en.wikipedia.org/wiki/List_of_equations_in_wave...

    A wave can be longitudinal where the oscillations are parallel (or antiparallel) to the propagation direction, or transverse where the oscillations are perpendicular to the propagation direction. These oscillations are characterized by a periodically time-varying displacement in the parallel or perpendicular direction, and so the instantaneous ...

  9. Coronal plane - Wikipedia

    en.wikipedia.org/wiki/Coronal_plane

    It is perpendicular to the sagittal and transverse planes. Details. The coronal plane is an example of a longitudinal plane. For a human, the mid-coronal plane would ...
