Final answer:
Fiber optic cables are not likely to be a source of electromagnetic interference (EMI), unlike power lines, motors, and microwaves.
Step-by-step explanation:
Electromagnetic interference (EMI) can be caused by various sources, such as power lines, motors, and microwaves. However, fiber optic cables are not likely to be a source of EMI.
Power lines can produce electromagnetic fields that may interfere with electronic devices, especially if they are not properly shielded. Motors, such as those used in machinery or appliances, can also generate EMI due to the electrical currents flowing through them. Microwaves, which operate at high frequencies, can also produce electromagnetic radiation that may interfere with electronic equipment.
On the other hand, fiber optic cables do not generate electromagnetic fields. They use light signals transmitted through thin strands of glass or plastic, which are not susceptible to EMI.
