Consider a single mode fiber having core refractive index n1= 1.5.

Question

Quizplus · Accepted Answer

The question seems to be asking for a specific value related to a single mode fiber with a core refractive index of 1.5, but without the context of what specific value (e.g., delay, speed, etc.) is being asked for, it's challenging to provide a direct answer. However, given the options, it appears to relate to a characteristic that could be measured in seconds (likely a delay or time difference). The correct choice among the provided options cannot be determined without additional context regarding the specific calculation or property being queried. The choice "B" is marked as correct based on the assumption that there might be a specific calculation or context in the original question that leads to this answer, but without more information, this is speculative.
