20.500.12556/RUL-169585 Sence v odbiti svetlobi magistrsko delo Shadows in reflected light Svetloba in sence sta dva zelo zanimiva pojava v naravi, ki vplivata na našo zaznavo okolja. Če ju natančno opazujemo, lahko opazimo določene zanimivosti. V magistrski nalogi gre za izviren problem, ki temelji na raziskovanju senc. V članku Does a virtual image cast a shadow? je opisan nastanek dvojne sence. Ta nastane, ko se svetloba odbije od neke odbojne površine. Glavni namen magistrske naloge je, da z uporabo razmislekov iz članka ustvarimo model, ki bi omogočal povečati število nastalih senc za predmetom, ki ga osvetljuje le en vir svetlobe. Te okoliščine lahko ustvarimo z odboji svetlobe na različnih površinah. S pomočjo različnih kombinacij zrcal in stekel je mogoče povečati število senc. Po teoretičnem razmisleku o tem, kaj ponujajo različne kombinacije zrcal in stekel, sem ugotovitve preverila še s poskusi, ki so se ujemali s teoretičnimi razmisleki. Prav tako pa sem raziskovala, kako odbojnost pri različnih kombinacijah in številu zrcal ter stekel vpliva na to, da so svetlobne lise in sence bolj ali manj svetle. Model in ugotovitve, ki smo jih pridobili, bi lahko uporabili tudi pri samem pouku naravoslovja ali fizike v šolah. Light and shadows are two fascinating phenomena in nature that influence our perception of the surroundings. By carefully observing them, we can notice interesting occurrences. This master thesis addresses an original problem based on the study of shadows. In the article "Does a virtual image cast a shadow?", the formation of a double shadow is described, which occurs when light is reflected from a reflective surface. The main aim of the thesis is to use the considerations from the article to create a model that would increase the number of shadows formed behind an object illuminated by a single light source. These conditions can be created by light reflections on various surfaces. Through different combinations of mirrors and glass, it is possible to increase the number of shadows. After considering theoretical aspect of what different combinations of mirrors and glass offer, I tested the findings through experiments, which matched with the theoretical considerations. I also explored how the reflection of various combinations and numbers of mirrors and glass affect the light spots and shadows to appear brighter or darker. The model and findings could also be used in science or physics classes in schools.
