Polarized light pollution information


In nature, water and water vapor polarize natural sunlight in other planes than vertical.
The eye facets of Platycnemis pennipes collect light directly or incidentally. That gives environmental information to the insect

Polarization is a property of light waves that describes the orientation of their oscillations. 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 of natural or artificial light can disrupt the behavior of these species and the ecosystems in which these species play an important role. Pollination is one example of this.
