What time in seconds is required for a signal to travel

Reference no: EM13691371

Please show me how you do the following problem:

Problem: Components of some computers communicate with each other through optical fibers having an index of refraction of 1.56.

A- What time in seconds is required for a signal to travel 0.20 m through such a fiber?

I need help to solve the above problem and thanks in advance.
