TL;DR: In this paper, the authors provided a quantitative account of the repolarization of skylight transmitted through a flat water surface and calculated the shape of the refraction-polarization oval at the air-water interface as functions of the polarization characteristics and the incident angle of partially linearly polarized incoming light.

TL;DR: It is demonstrated experimentally that the refraction of chemical waves obeys Snell's law and does not show specular reflection, but rather exhibit a single reflection angle, equal to the critical angle.
Abstract: When a chemical wave encounters a boundary between two media with different wave speeds, refraction and reflection can occur. We demonstrate experimentally that the refraction of chemical waves obeys Snell's law. Reflection of chemical waves has been observed for the first time. The waves do not show specular reflection, but rather exhibit a single reflection angle, equal to the critical angle

TL;DR: The celestial polarization pattern may be scrambled by refraction at the air-water interface and this polarization pattern was examined in shallow waters with a submersible polarimeter, and it was calculated by using land measurements and models of the skylight polarization.
Abstract: The celestial polarization pattern may be scrambled by refraction at the air-water interface. This polarization pattern was examined in shallow waters with a submersible polarimeter, and it was calculated by using land measurements ('semiempirical predictions') and models of the skylight polarization. Semiempirically predicted and measured e-vector orientations were significantly similar. Conversely, predicted percent polarization was correlated but lower than measurements. Percent polarization depended on wavelength, where at high sun altitudes maximal percent polarization generally appeared in the UV and red spectral regions. The wavelength dependency of polarization may lead to differential spectral sensitivity in polarization-sensitive animals according to time and type of activity.

TL;DR: An analysis is made of the various possible paths traveling from one medium to another and it is demonstrated that the most efficient possible path for traveling in the shortest possible time is the path determined by Snell's Law.
