Oblika vzvalovane gladine in lom svetlobe

Brolih, Anita (author), Čepič, Mojca (mentor)

V magistrskem delu sem obravnavala lom svetlobe na vzvalovani gladini in profil intenzitete svetlobe pod njo. Osredotočila sem se predvsem na področja s povečano intenziteto svetlobe oziroma kavstike. Ta področja so najbolj vidna v motni valujoči vodi. Vidna postanejo zaradi sipanja svetlobe na majhnih delcih v vodi. Svetlobni curki se pod vodo sekajo v več goriščih, zato nastane mreža kavstik. Predstavila sem, zakaj se mreža kavstik pojavi, kako jo lahko opazujemo in kako oblika gladine, na kateri se svetloba lomi, vpliva na mrežo kavstik. Analizirala sem različne primere neenostavnih površin ter njihov vpliv na začetno lego kavstike in njen razcep. Skušala sem ugotoviti tudi obratno, in sicer ali in kako lahko iz mreže kavstik sklepamo na obliko gladine.

• Title: Wavy water surface form and light refraction

Abstract

The goal of this work is to describe refraction of light on ruffled water surface and the intensity of light profile below it. The focus is on the area with increased intensity of light, that is the caustic. These areas are the most visible in wavy and unclear water. They can be observed due to the scattering of light on small, sandy particles present in the water. Light beams are intersected under water surface in several focal points, and by that the caustic network is formed. I described why is the caustic network phenomenon, how can we observe it and how the shape surface, at which the light refracts, affects the caustic network. I analyzed various examples of complex surfaces and their impact on the starting position of the caustic and its splitting. I also tried to analyze the opposite, how the shape of water surface can be deduced from the caustic network.
