2. Refraction
3. Radiation
4. Noise
2. Refraction
The important property of fiber optic you are referring to is refraction. Fiber optic cables rely on the principle of refraction to transmit light signals over long distances. Refraction occurs when light passes from one medium to another, causing the light to bend. In the case of fiber optic cables, the light signals travel through the core of the cable, which has a higher refractive index than the surrounding cladding material. This causes the light signals to be internally reflected within the core, allowing them to travel along the cable without significant loss.
To find the correct answer, you can eliminate the options that are not related to the property of fiber optic cables.
1. Degradation: While fiber optic signals can degrade over long distances, degradation is not a specific property of fiber optics.
2. Refraction: Refraction is indeed an important property of fiber optic cables.
3. Radiation: Radiation is not a specific property of fiber optic cables, as they are designed to minimize the emission of electromagnetic radiation.
4. Noise: While fiber optic signals can be affected by noise in certain situations, noise is not a specific property of fiber optic cables.
Therefore, the correct answer is 2. Refraction.
The correct answer is 2. Refraction.
Fiber optics is a technology that uses thin strands or fibers of glass or plastic to transmit data in the form of light pulses. One of the important properties of fiber optics is refraction, which refers to the bending of light as it passes from one medium (such as air) to another (such as the fiber optic material). This property allows the light signals to be transmitted along the length of the fiber optic cable without significant loss or degradation. Refraction also helps to prevent dispersion, which is the spreading out of light signals, enabling the transmission of data over long distances without significant loss in signal quality.
