FOA Lecture 23: Total Internal Reflection in Optical Fiber

This video is Lecture 23 in the Fiber Optics Association's series of lectures on fiber optics. This lecture discusses "refraction" and "total internal reflection." "Total internal reflection is important in fiber optics as it is the reason that light can be trapped in the core of the fiber, making optical fiber transmission possible." A visible red laser from a VFL is used to demonstrate total internal reflection in a large core plastic fiber. Running time for the lecture is 5:03 minutes.
