Light at the End of the Tunnel: An Introduction to the Study of Fiber Optics

The Materials Science and Technology Teacher's Workshop (MAST) provides this experiment on fiber optics. The lesson aims to show that light will travel down a glass tube because of internal reflection. This module will help students understand the physical properties that allow fiber optics technology to work. The lesson includes a step by step explanation of the laboratory procedure, discussion questions, and a link to a video clip.
