 Lab Equipment  Directions
  1.  Flask with pine-sol on stand
  2. laser (or handheld laser)
  1.  Shine the laser up through the solution as shown.
  2. If the angle of incidence is small, the beam will be refracted as it exits out the top surface of the liquid.
  3. As the angle of incidence becomes larger at the critical angle the beam will undergo total internal reflection.
