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 appropriaten value isted in the table below. After doing so, set the index of refraction for the lower half matel (wer) 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.

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 (u), and then use Snell's Law to calculate the index of refraction for Mystery A (nu). 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). op HR / 1 180 + tình tan PM (degrees) n Trial 1 1.19 25 Trial 2 1.38 30 Trial 3 1.59 35 ✓2.55 2.5 2.51 relative uncertainty x 100 AM TIM 116 096 083 7.
