A fiber-optic cable consists of a thin cylindrical core with thickness d made of a material with index of refraction n surrounded by cladding made of a material with index of refraction n₂n. Light rays traveling within the core remain trapped in the core provided they do not strike the core-cladding interface at an angle larger than the critical angle for total internal reflection. Figure AL= 0.404 m Submit Previous Answers ✓ Correct Part E How much longer would it take light to travel 1.00 km through the cable than 1.00 km in air? Express your answer to three significant figures and include the appropriate units.
