What medium does information travel through in optic fiber?

• A. Electrons
• B. Photons
• C. Ultrasound
• D. Microwaves

Answer: (B)

In optic fiber, information travels through photons, which are particles of light. Optic fibers are designed to transmit light over long distances, using the principle of total internal reflection. When light enters an optical fiber, it reflects off the inner walls of the fiber at a certain angle, allowing the light to travel through the fiber with minimal loss of signal. Photons are essential in this process because they carry the data in the form of light signals. This method of communication is advantageous due to its high bandwidth capability and lower attenuation when compared to electrical signals in traditional copper wires. This enables the transmission of large amounts of data quickly and efficiently. The other options do not apply to optic fiber technology. Electrons are associated with electric signals in conductors like copper wires. Ultrasound utilizes sound waves, which do not travel through fiber optics, and microwaves involve electromagnetic waves that are typically used for different types of wireless communication rather than being transmitted through fiber.
