6A44.40 - Fiber Optics Light Pipes


Fiber Optics Light Pipes Demo
Fiber Optics Light Pipes Demo



Code: 6A44.40


Demo Title: Fiber Optics Light Pipes


Subject: Total Internal Reflection


Description:
Fiber optics transmit light (information) via total internal reflection, with negligible loss of energy


Procedure:

  • Demonstration of how a green and red laser is transmitted through fiber optics with the help of various transparent light pipes.
  • Using the simple plastic tube, shine laser across the width.
  • Next place the laser at the end and shine it through the entire length of the tube.
  • Using the curved plastic tube repeat the process.
  • Turn on the fiber optics lamp in the front of the desk and the fish lamp in the rear.(turn off lights at this point)
  • Use laser and point in the far end of the fiber optic cable.
  • Repeat this process with the fiber optics model on the stand and the lens on the rod.
  • Turn on the lasers on the stand and direct their beam at the larger fiber optics model. Use the diffraction grating to split the light.
  • Alternate between the green and the red laser.
  • Review how fiber optics work and what they are used for.
