# Problem: Components of some computers communicate with each other through optical fibers having an index of refraction n = 1.55. What time in nanoseconds is required for a signal to travel 0.200 m through such a fiber?

###### FREE Expert Solution

In this problem, we'll apply the relationship between speed, distance, and time. We'll also need the relation between velocity and refractive index.

Time:

$\overline{){\mathbf{t}}{\mathbf{=}}\frac{\mathbf{d}}{\mathbf{v}}}$
