PROBLEM: How can you distinguish between diffraction, reflection, and refraction of waves?

PREDICTION:

PROCEDURE: Go to the different stations and determine if the wave is physical or electromagnetic. Perform the activity and determine whether you are showing diffraction, reflection or refraction. Remember LASER SAFETY.
