Complete Table 3 by computing the sine of the incident and refracted angle. 6. Plot a graph of sin(0i) versus sin(Or). Construct your graph on a computer program such as Microsoft Excel@. If you do not have a graphing program installed on your computer, you can access one on the internet via the NCES website or the Online Chart Tool. 7. Add a linear trendline and display the equation on the graph. In the Error Analysis section of your report, combine the measured index of refractions from the slope and question 1 as an uncertainty range by averaging the two values and taking two-thirds the difference between them as uncertainty (e.g., 1.28 +/-0.03). Estimate the precision level from the uncertainty range, the accuracy level from the accepted value for the water's index, and discuss whether any systematic errors seem present from this comparison
