Question
as radius of fiber increases the number of modes __________Select one:a. increaseb. decreasec. not dependentd. remains same
Solution
The answer is a. increase.
Here's why:
The number of modes in a fiber is directly proportional to the square of the fiber's radius. This means that as the radius of the fiber increases, the number of modes that can propagate through the fiber also increases.
In simpler terms, a larger fiber can support more paths (or modes) for the light to travel through. This is because there is more space within the fiber for the light to bounce around.
So, if you increase the radius of the fiber, you increase the number of modes.
