Abstract
Diplomsko delo zajema računalniško simuliranje, v katero je vključena metoda Monte Carlo. Metodo najprej predstavim, na kratko povzamem njeno zgodovino in opišem njene sestavne dele. V nadaljevanju opišem nekaj lažjih primerov računalniških simulacij in predstavim njihove rezultate. Ti primeri so: računanje približka števila π, naključna hoja v eni dimenziji, naključna hoja v dveh dimenzijah in nevtronski reflektor. Problemi si sledijo po zahtevnosti od najpreprostejšega do najzahtevnejšega. Nazadnje predstavim še glavni problem dela, to je sipanje svetlobe v atmosferi. Opišem tudi računalniško simulacijo in njene rezultate. Preko izračunov in grafov pojasnim, zakaj je nebo modro in zakaj je sonce ob sončnem zahodu rdeče. Vključila sem tudi sliki neba in zahajajočega sonca, ki sta obarvani glede na deleže posamezne osnovne barve, pridobljene z računalniško simulacijo.

Title:Computer simulation of light scattering in the atmosphere
Abstract:
In my diploma thesis I present computer simulation based on the Monte Carlo method. In the beginning I describe the method and some history behind it. I also present its components, which are important for using the method. In the following chapter, I present some simple examples of computer simulations. They are organized by difficulty, from basic to the more complicated ones. These examples are: calculating the mathematical constant π, random walk in one dimension, random walk in two dimensions, and neutron reflector. After that I introduce the main problem of the thesis, light scattering in the atmosphere. I describe the problem and its implementation in the computer simulation in detail. Using the results of my calculations I explain why the sky is blue when the sun is in the zenith and also why the sun is red at the sunset. I also made a picture of the sky and of the sun at the sunset, which are coloured according to the results of simulation.
