Fiber optics is simply strands of flexible glass as thin as human hair that is used for telecommunications. .. These strands carry digital signals with . light.. When hundreds or even thousands of these strands are arranged in bundles, it is called an optical cable.. Raytracing. Lecture 7: Optics. UCSD Physics 122. 2. Reflection. We describe the path of light as straight-line rays. “geometrical optics” approach. Reflection off a flat surface follows a simple rule:.
