Which phenomenon is essential for the functioning of optical fibers?
Understand the Problem
The question is asking about the essential phenomenon that allows optical fibers to function correctly. This involves understanding the principles of light behavior, particularly in the context of optical fiber technology.
Answer
Total internal reflection.
The final answer is total internal reflection.
Answer for screen readers
The final answer is total internal reflection.
More Information
Total internal reflection occurs when a light wave traveling through a denser medium hits a less dense medium at an angle greater than the critical angle, ensuring the light is completely reflected back into the denser medium. This principle is crucial for guiding light through the core of optical fibers.
Tips
A common mistake is confusing total internal reflection with refraction or simple reflection. Total internal reflection requires specific conditions where light reflects entirely within the denser medium.
