5. Fill in the table below by using the Index of Refraction slider to set the index of refraction (n) for the upper half material to the values in the table below, record the angle of refraction (Oul, and then use Snell's Law to calculate the index of refraction for Mystery A (ny). To determine the uncertainty of that calculation (), use the formula shown above the table on the left. Additionally, determine the relative uncertainty of each ny by using the formula above the table on the right. The relative uncertainty lets you know how precise your value is (smaller is better). on= Trial 1 Trial 2 180 tano tan n; 1.15 25 1.4 29 Trial 3 1.54 35 1) AM [degrees) Trial 1 Trial 2 Trial 3 I✓ 2.48 2.37 180 relative uncertaintynx 100 ПМ 1.15 1.2 1.47 7.

Change the upper half material to Mystery A and change the lower half material to Air. After doing so, it should look like the screenshot below. Notice that total internal reflection is occurring. relative uncertainty of nu Incerta (%) Prediction from Value from Power formula for Ocnit simulation for Vent (degrees) (degrees) 9. For the table below, use the formula for Total Internal Reflection to predict what the critical angle will be. For this calculation, use the average n value you previously determined and the appropriate n value listed in the table below. After doing so, set the index of refraction for the lower half material (nower) to the appropriate value listed in the table below. Then determine the critical angle by moving the laser and finding the smallest angle (relative to the normal) at which no refraction occurs. This angle is the critical angle. Record it in the table below.
