  2. Polarized light pollution - Wikipedia

    en.wikipedia.org/wiki/Polarized_light_pollution

    Polarized light pollution [1] is a subset of the various forms of light pollution referring specifically to polarized light. In nature, water and water vapor polarize the sunlight (which itself is slightly polarized). By receiving the direction of polarized photons, some species can correct their course during migration. Artificial polarization ...

  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. Extinction (optical mineralogy) - Wikipedia

    en.wikipedia.org/wiki/Extinction_(optical...

    Extinction is a term used in optical mineralogy and petrology, which describes when cross-polarized light dims, as viewed through a thin section of a mineral in a petrographic microscope. Isotropic minerals, opaque (metallic) minerals, and amorphous materials (glass) do not allow light transmission under cross-polarized light (i.e. constant ...

  5. 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.

  6. Optical phenomenon - Wikipedia

    en.wikipedia.org/wiki/Optical_phenomenon

    One common example is the rainbow, when light from the Sun is reflected and refracted by water droplets. ... Polarized Light in Nature, G. P. Können, ...

  7. Circular polarization - Wikipedia

    en.wikipedia.org/wiki/Circular_polarization

    The rose chafer's external surface reflects almost exclusively left-circularly polarized light. Only a few mechanisms in nature are known to systematically produce circularly polarized light. In 1911, Albert Abraham Michelson discovered that light reflected from the golden scarab beetle Chrysina resplendens is preferentially left-polarized.

  8. Rayleigh sky model - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_sky_model

    While all scattered light is polarized to some extent, light is highly polarized at a scattering angle of 90° from the light source. In most cases the light source is the Sun, but the Moon creates the same pattern as well. The degree of polarization first increases with increasing distance from the Sun, and then decreases away from the Sun.

  9. Brewster's angle - Wikipedia

    en.wikipedia.org/wiki/Brewster's_angle

    Polarized sunglasses use a sheet of polarizing material to block horizontally-polarized light and thus reduce glare in such situations. These are most effective with smooth surfaces where specular reflection (thus from light whose angle of incidence is the same as the angle of reflection defined by the angle observed from) is dominant, but even ...
