Use an on-line simulation from the University of Colorado PhET group to explore the bending of light. Link to the simulation: https://phet.colorado.edu/en/simulations/bending-light Explore the interface! Tools and objects can be dragged out of the tool box and then returned. The objects in the Prisms tab can be rotated by dragging the handle. In the Prisms tab, the protractor rotates and the laser translates. All the tools work in both Ray and Wave mode, but some are easier to use in Wave mode because the region where the tool can read is larger. Click on either the Intro or More Tools tab. Let red light move from air into water. (Make sure you select water if you click the More Tools tab.) For incident angles i from zero to 80o in 10 degree steps measure the angle of refraction t and the reflected intensity or reflectance R. Download this spreadsheet and enter your measured values on sheet 1. Plot R versus theta. Paste your graph into your log. Compare to the graph above. Discuss your result. Is the laser light p-polarized, s-polarized, or unpolarized. What do your results suggest? Calculate sini and sint. Remember that Excel functions require the angles to
