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?

Discussion: Research Design and t Tests: How Are They Connected?Whether in a scholarly or practitioner setting, good research and data analysis should have the benefit of peer feedback. For this Discussion, you will perform an article critique on t tests. Be sure and remember that the goal is to obtain constructive feedback to improve the research and its interpretation, so please view this as an opportunity to learn from one another.To prepare for this Discussion:Review the Learning Resources and the media programs related to t tests.Search for and select a quantitative article specific to your discipline and related to t tests. Help with this task may be found in the Course guide and assignment help linked in this week’s Learning Resources. Also, you can use as a guide the Research Design Alignment Table located in this week’s Learning ResourcesBy Day 3Write a 3- to 5-paragraph critique of the article. In your critique, include responses to the following:Which is the research design used by the authors?Why did the authors use this t test?Do you think it’s the most appropriate choice? Why or why not?Did the authors display the data?Do the results stand alone? Why or why not?Did the authors report effect size? If yes, is this meaningful? Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.
