Bending Light Simulation Go to the Bending Light simulation and click the "More Tools" option upon running the simulation. 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? If you were to slide the button to the left, the angle of refraction would likely increase. This is because sliding the button to the left decreases the refraction index, which lessens the degree to which the angle is refracted. 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. The refraction index of this material is 1.449, this figure was calculated using snell’s law 3. Do you expect the light to be moving faster in the top material or the bottom material? Why? I expect light to travel faster in the top material, as it has a lower refractive index than glass of 1.449 which allows light to travel at a faster speed. 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? If you tilt the laser to an angle of greater than 46% then total internal reflection begins to happen, because the critical angle was exceeded.
