Refraction and Total Internal Reflection

Posted on January 1, 2011 by Arbor Scientific

Refraction and Total Internal ReflectionStudents will be able to observe that refraction (bending) always takes place at the interface between two different transparent materials and that the angle of refraction in plastic is smaller than the angle of incidence in air. The light is directed at the center of the semicircular cup where it is [...]

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!
