Unformatted text preview: Kimberly Hargraves Physics Lab part #3 Refraction and Ray Box April 16, 2011 Part III. Using a ray box and a glass prism, the angle of incidence and the angle of refraction was determined and measured. There is a right and a left side to each angle. These two angles allowed the index of refraction to be calculated by using Snell’s law. Two different medium were used. The first medium that was used water and the second medium was alcohol. The known index of refraction of water is 1.33. The known index of refraction of alcohol is 1.36. The known and experimental value of index of refraction of each medium was compared to give the percent error. Three runs were performed. In this lab, the glass prism was filled with water. In run one, the angle of incidence and the angle of refraction on the left side is 42.5 and 32 degrees respectively. The right side in run one the angle of incidence and the angle of refraction is 40 and 27.5 degrees respectively. The left side index of refraction is 1.27 and compared to the known value of 1.33, an -4.5% error exist. The right side index of refraction is 1....
