The figure shows an optical fiber in which a central plastic core of index of refraction n1 = 1.66 is surrounded by a plastic sheath of index of refraction n2 = 1.47. Light can travel along different paths within the central core, leading to different travel times through the fiber. This causes an initially short pulse of light to spread as it travels along the fiber, resulting in information loss. Consider light that travels directly along the central axis of the fiber and light that is repeatedly reflected at the critical angle along the core-sheath interface, reflecting from side to side as it travels down the central core. If the fiber length is 330 m, what is the difference in the travel times along these two routes? 39371

In an optics lab, an experiment is performed using two identical lasers and two identical photodetectors. Each detector is the same fixed distance away from the emitter of each laser. Light emitted from the first laser travels only through air before reaching the detector. Light emitted from the second laser first travels through a 6.10 m long column of diamond before emerging in air and continuing to the detector. The index of refraction of diamond is 2.419. The lasers each emit a pulse of light simultaneously. What will be the difference in the times of arrival of the two pulses at the detectors (in ns)? ns
