5. Using the same simulation (prism option), set up the following refraction examples for the semi-circular prism below, and show the light path through the material. In your simulation, keep your laser fixed, and rotate the semi-circular glass. Use the "Normal" and "Protractor" Setting, rotating the protractor so that the "zero degrees" is always matched up with the dotted normal line. How Rotate the protractor with the prism to maintain a consistent angle coordinate system. many kinks are in each of the setups shown below? How is this system simpler than the rectangular prism system in Question 4? T
