Bending Light Simulation Go to the Bending Light simulation and click the "More Tools" option upon running the simulation. ( https://phet.colorado.edu/sims/html/bending-light/latest/bending-light_en.html ) This the link Once on this page, check the "angles" box in the bottom left hand corner. The index of refraction for the bottom material is automatically set to glass. Turn the laser on by pressing the red button. Answer the following questions: 1. If you were to slide the button down to the left for this material, do you expect the angle of refraction to increase or decrease? Why? Put the bottom material back to glass. Change the top material to "Mystery B" in the drop down menu. 2. What is the index of refraction of this material? How did you figure this out? You can check your answer by switching the material to Custom. 3. Do you expect the light to be moving faster in the top material or the bottom material? Why? Switch the option in the top left corner from "Ray" to "Wave". Check your answer by dragging the speed tool over both laser paths to see if you were correct. 4. If you tilt the laser to an angle greater than 46%, what begins to happen?

Hi! I need a 1 page annotation for this story. If anyone can please help me on this, I'd really appreciate it!
