Question1- Were your values of the index of refraction nearly equal with a reasonably small percent deviation, what specific defects in the apparatus or procedure might have contributed to these variations?
Question 2- Complete the sketch below, showing approximately how a light ray is bent twice in passing through a prism. (Remember, Snell's law suggests that a light ray will be closer to the normal on the glass side of the boundary than on the air side. Draw in the normal line where the light ray passes through the right side of the prism. An exact drawing is not possible since the exact index of refraction is not known for this particular piece of glass.) Is the index of refraction the same for all colors of light? What happens when white light is bent by a prism?
