Describe the shape of your graph. BIU E E A I used sin function to linearize the graph sin angle of incidence= k sin angle of refraction sin angle of refraction= k sin angle of incidence Score: 0/1K J '532' 1. What is the relationship between angle of incidence and angle of refraction? i What function will you use to linearize the data? Apply this by creating two new columns to your data table which will calculate these values (use the Change Column Formula to apply the calculation]. (6'3 \\___/ Hint: Remember that Snell's Law is: Sinai\" = kss'nmf or more commonly written as: ss'nb'l _ m 52'an n1 lire value can be calculated automatically by using the "change column formula'f BIH ol2l the relationship between angle of incidence and angle of refraction by snells law states that the ratio of the sine of the angle of refraction and the sine of the angle of incidence is always constant and equivalent to the ratio of phase velocities of the two mediums it is passing through. 2. Graph the new relationship to find the the index of refraction of the transparent block. Describe your process below. Hint: There is no calculation to preform. Use the value from your linear equation. BIUE E E Score: 0/13. According to the manufacturer, the index of refraction for this sample of the transparent block is 1.5. Calculate the percent difference between this value and your measured value. Comment on the experimental design and possible sources of error. Hint: Include your calculation. When talking about experimental design really think about what you could change about the procedure and apparatus. If your only response is to "measure more accurately next time" then redo the experiment now, measure more accurately, and come up with something else. BI U E PA Score: 0/1
