6A44.45 - Fiber Optics - Water Stream Light Pipe

Code Number:
Demo Title:
Fiber Optics - Water Stream Light Pipe
Critical Angle and Total Internal Reflection
Area of Study:
Plexiglas Water Tank with Side Hole, and Laser.

Shine the laser through the Plexiglas water tank so that the beam exits the tank through the hole in the side.  Fill the tank with water so that the water is above the level of the laser beam.  The beam will follow the stream of water for an impressive display of internal reflection and critical angle.
