Question
as radius of fiber increases the number of modes __________Select one:a. remains sameb. decreasec. increased. not dependent
Solution
The answer is c. increase.
Here's why:
In fiber optics, the term "mode" refers to the path that light takes when traveling down the fiber. The number of modes is directly related to the diameter of the fiber - the larger the diameter, the more paths (or modes) the light can take.
So, as the radius (which is half the diameter) of the fiber increases, the number of modes also increases.
