Follow the instruction and finish the following tasks (a) Click the red button to enable the light beam. Move the protractor to the center of the picture, it should measure the initial incident angle as 45 degrees. Water has the index of refraction of 1.33. Use Snell's Law and calculate the angle of refraction in this initial setting to be 32.12 degrees. Then compare your calculation to what you can read from the simulation (b) Select the material of the lower side to be "Mystery A", select the material of the upper side to be "Water" (which has the index of 1.33). Use the same incident angle of 45 degrees What is the angle of reflection? 13.5 x degrees. What is the angle of refraction that you read from the simulation? 24 degrees (c) Use Snell's Law and calculate the index of refraction of this mystery A material 2.149 Check table 1-1 of your textbook, which of the following is most likely to be the mystery A" material? Diamonde (d) Use the index you got in the previous part to calculate the total internal refraction critical angle if a light beam incident from the "mystery A' material into the water. degrees 335 (e) Change the material of the upper side to be "Mystery A", change the material of the lower side to be "Water Adjust the position of the beam light to find the critical angle of this total internal refraction.
