What is a common application of optical fibers?

Optical fibers are designed specifically to transmit light with minimal loss over long distances. They are made from materials like glass or plastic that allow light to travel through them by the principle of total internal reflection. This ability to transmit light efficiently makes optical fibers ideal for a variety of applications, including telecommunications, internet data transfer, and medical instruments.

While sound, electricity, and radio waves can be transmitted using different mediums and technologies, they are not the primary function of optical fibers. Instead, optical fibers excel in applications that require high-speed data transmission through light signals, making them a fundamental component of modern communication systems.
