The Fiber Optics Principle

Posted on January 1, 2011 by Dean Baird

Students discover that magic is really science... Students got so fascinated with air to water refraction that they raced ahead to explore other possibilities. One group called me over when they found that when the laser beam hit the water to air boundary at a certain angle, it got trapped. They had discovered the secret of Total Internal Reflection and fiber optics for themselves!

Reflection & Refraction

One day in my classroom...“My students were amazed by examples of colorful fiber optics but didn't understand how the light goes from one end to the other; even when bent. After testing various angles of laser light through water and air up to 40 degrees, most students assume the light will continue to exit the other side.
