So does change in time = t zigzag - t direct = n1^2*L/n2*c - n1*L/c?

Figure 35-57 shows an optical fiber in which a central plastic core of index of refraction n1  1.58 is surrounded by a plastic sheath of index of refraction n2  1.53. Light can travel along different paths within the central core, leading to different travel times through the fiber.This causes...
