Z5109208 HAIMEI ZHAOnwatersinα1=nairsinα2 of Snell’s law, the refractive index of water can beobtained.4. First of all, according to nwatersinα1=nairsinα2 given by Snell’s law, weknow that the product of the refractive index of the water and the angleof refraction is equal to the product of the refractive index of air and theangle of incidence. Based on this conclusion, we can infer that becausethe refractive index of water is diferent from the refractive index of air,the chopstick look like bend in the water. What’ more, because thedensity of water is not the same as the density of air, the refractive indexwill be diferent, causing the chopstick to appear bend in the water. Inthe following diagram, S is the actual position of the chopstick, and S’ isthe virtual image of the chopstick. It is obvious that the position of thevirtual image is higher than the actual position, so the chopstick appearto be bend.ConclusionIn this experiment I explained why the object appears to be curved in thewater and studied the relationship between the angle of incidence andthe angle of refraction. What’s more, using Snell’s law to help me findthe refractive index of water, although there are errors in theexperimental results, I proposed a way to improve the accuracy of theexperimental results.
