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.
