How would you answer these questions from this virtual lab?

1. Design a data table
2. In the virtual investigation, select ray in the top right-hand corner.
3. Select the top material as air and the bottom material as water.
4. Place the protractor along the normal line (0). Use the green arrows to move the laser pointer to 0 (in the air). Turn the laser pointer on. The resulting angle of refraction should be zero.
5. Record the angles of refraction for incident angles from 10 to 70 in 10 increments.
6. Record your data on your data table.
7. Plot a graph of sin angle of incidence vs. sin angle of refraction for water. Calculate the slope of this graph.
8. Repeat steps 1 through 7 for Mystery substance B.
