Polarised light pollution on river water surfaces caused by artificial light at night from illuminated bridges and surroundings
PublicationLight is the part of the electromagnetic spectrum visible to the human eye, and such electromagnetic waves can be polarised (Foster et al., 2018) (Supplementary Material). Generally, humans are not able to perceive polarised light, apart from some very specific situations (Haidinger, 1844), while several animals are able to perceive it (Foster et al., 2018). Polarisation can occur when unpolarised light is reflected or transmitted...
