Question
he maximum distance that can be travelled without dispersion increases with ___________ in wavelength.Select one:a. increaseb. decreasec. not dependentd. remains same
Solution
The answer is a. increase.
The maximum distance that can be travelled without dispersion increases with an increase in wavelength. This is because dispersion, which is the spreading of light pulse as it travels down the fiber, is inversely proportional to the wavelength of the light. Therefore, as the wavelength increases, the dispersion decreases, allowing the light to travel a greater distance without dispersion.
