Answer:

Because of the chemical makeup of the fiber.

Explanation:

The birefringence is the difference between the refractive index of a fiber in a direction at parallel to the fiber axis and in a direction at right angles. It is caused by asymmetric core shape for the two axes, and majorly one of the manufacturing imperfections. It helps in controlling polarization property inside the fiber.

Inevitable manufacturing imperfections in optical fiber leads to birefringence, which is one cause of pulse broadening in fiber-optic communications. Such imperfections can be geometrical (lack of circular symmetry), due to stress applied to the optical fiber and/or due to bending of the fiber.

When the nail was copper-plated in Part III of the lab, what element do you think was reduced? Explain your answer in complete s

Jet001 [13]

Reduction always results in a lowering of the oxidation number. The reaction of the system above is written as:

Cu2+(aq) + Fe(s) --> Cu(s) + Fe2+(aq)

From the reaction, we see that copper goes from the +2 to a neutral charge. Lowering of the oxidation number happens so this is the element that is being reduced.
