PHet Lab: Bending Light

Go to the link here. Click on Intro.

Move the protractor and line it up with the surface of the interface between the two materials.

Press the red button to turn on the laser.

For each scenario, select the top and bottom material as specified in each data table. Record the index of refraction, n, for each material in the data table. Choose two incident angles between 5o – 85o for each scenario, and record the incident, reflected, and refracted angles in the table.

After filing in the table, draw the rays as they are in the sim.
