Predict the refracted angle, the for each of the pairs of materials using Snell's Law and record the values in the Data Table. Set Cato 30 degrees. 2. Predict if there will be Total Internal Reflection (TIR), if so, calculate the critical angle for each of the pairs of materials and record the values in the Data Table. 3. Open the "Bending Light" simulation https://phet.colorado.edu/sims/html/bending-light/latest/bending-light en.html and select the "More Tools" option. 4. Check the box "Angles" in order to display the angles on the screen. Page 1 of 3 REFRACTION AND REFLECTION OF LIGHT WORKSHEET 5. Confirm your predictions for the pairs of materials (for ( and (en). Attach a screenshot for each of your confirmations at the end of the worksheet. 6. Now set the Top Material to "Mystery A" and the Bottom Material to Air. Determine the index of refraction of "Mystery A" material. You may set 0 - 20 degrees. 7. Now set the Top Material to "Mystery B" and the Bottom Material to Air. Determine the index of refraction of "Mystery B" material. You may set On- 20 degrees. "Mystery A" Index of Refraction: on food/ sjobs - "Mystery B" Index of Refraction: De=(ciolo/ jobs - Questions: 1. Based on its index of refraction, what material was "Mystery A"? 2. Based on its index of refraction, what material was "Mystery B"? 3. Based on its index of refraction, which materials from the Data Table would have a critical angle when paired with the "Mystery A" material? 4. Based on its index of refraction, which materials from the Data Table would have a critical angle when paired with the "Mystery B" material
