  2. Plane of polarization - Wikipedia

    en.wikipedia.org/wiki/Plane_of_polarization

    This definition was all the more reasonable because it meant that when a ray was polarized by reflection (off an isotopic medium), the plane of polarization was the plane of incidence and reflection — that is, the plane containing the incident ray, the normal to the reflective surface, and the polarized reflected ray.

  3. Polarization (waves) - Wikipedia

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

    Polarized light with its electric field along the plane of incidence is thus denoted p-polarized, while light whose electric field is normal to the plane of incidence is called s-polarized. P-polarization is commonly referred to as transverse-magnetic (TM), and has also been termed pi-polarized or π-polarized, or tangential plane polarized.

  4. Optical rotation - Wikipedia

    en.wikipedia.org/wiki/Optical_rotation

    Dextrorotation and laevorotation (also spelled levorotation) [1] [2] in chemistry and physics are the optical rotation of plane-polarized light.From the point of view of the observer, dextrorotation refers to clockwise or right-handed rotation, and laevorotation refers to counterclockwise or left-handed rotation.

  5. Brewster's angle - Wikipedia

    en.wikipedia.org/wiki/Brewster's_angle

    Brewster's angle is often referred to as the "polarizing angle", because light that reflects from a surface at this angle is entirely polarized perpendicular to the plane of incidence ("s-polarized"). A glass plate or a stack of plates placed at Brewster's angle in a light beam can, thus, be used as a polarizer.

  6. Linear polarization - Wikipedia

    en.wikipedia.org/wiki/Linear_polarization

    Diagram of the electric field of a light wave (blue), linear-polarized along a plane (purple line), and consisting of two orthogonal, in-phase components (red and green waves) In electrodynamics , linear polarization or plane polarization of electromagnetic radiation is a confinement of the electric field vector or magnetic field vector to a ...

  7. Specific rotation - Wikipedia

    en.wikipedia.org/wiki/Specific_rotation

    For an optically active substance, defined by [α] θ λ = α/γl, where α is the angle through which plane polarized light is rotated by a solution of mass concentration γ and path length l. Here θ is the Celsius temperature and λ the wavelength of the light at which the measurement is carried out. [2]

  8. Polarization in astronomy - Wikipedia

    en.wikipedia.org/wiki/Polarization_in_astronomy

    Continuum light is linearly polarized at different locations across the face of the Sun (limb polarization) though taken as a whole, this polarization cancels. Linear polarization in spectral lines is usually created by anisotropic scattering of photons on atoms and ions which can themselves be polarized by this interaction.

  9. Polarimetry - Wikipedia

    en.wikipedia.org/wiki/Polarimetry

    Plane polarized light: According to the wave theory of light, an ordinary ray of light is considered to be vibrating in all planes of right angles to the direction of its propagation. If this ordinary ray of light is passed through a nicol prism, the emergent ray has its vibration only in one plane.
