Optics: Reflection and Refraction
... The light that goes into the fiber totally reflects at the interface between the core of the fiber (with index of refraction n1) and the surrounding medium (with index of refraction n2). The path of the light thus follows the shape of the fiber instead of traveling in a straight line. With such a de ...
