Abstract
V diplomski nalogi predstavljam pojav gravitacijskega lečenja. Najprej zapišem nekaj zgodovinskih ključnih dogodkov, ki so zanj spodbudili zanimanje. Nato opišem glavne značilnosti in v okviru Newtonove mehanike izpeljem enačbo za odklon svetlobnih žarkov ter zvezo med položajem objektov v vesolju in kotom, kjer opazovani objekt vidimo. Predstavim lomni zakon in plankonveksno lečo ter jo primerjam z lečo, ki bi lahko ponazorila gravitacijsko lečenje. Za slednjo izpeljem, kakšen prečni prerez mora imeti. V praktičnem delu predstavim poskuse, s katerimi bi lahko ponazorili obnašanje žarkov svetlobe in nastanek slik, kot to velja za gravitacijsko lečenje.

Title:
Demonstration of gravitational lensing with a simple model
Abstract:
My diploma thesis presents the astrophysics phenomen gravitational lensing. Firstly, first historical events of the phenomen are described. Secondly, some main characteristics of gravitational lensing are explained. By Newton's model of gravitation I derive the equation for deflection of light ray and the connection between objects' position and the position of the source image. I present the law of refraction and I compare plano-convex lens with lens that is used to show the characteristics of gravitational lensing. The shape of that lens is also derived. In the last part, I prepare some experiments with right shaped lens to introduce the phenomen.
