Today in class we did an experiment which shows how light changes in different mediums, we used a semi-circle shaped clear-plastic cup and poured a quarter of water into it. Then we placed it on graph paper on a center like and outlined it. Then we drew lines on the graph that point toward a line on the cup, one on flat side, one on curved side. Then we figured out the angle of incidence and angle of reflection and then divided the sin of angle of incidence by the sin of angle of refraction to get n.
