Other users will ask the following questions:
1.Why does light have a speed limit?
Nothing can travel faster than 300,000 kilometers per
second (186,000 miles per second). Only massless particles,
including photons, which make up light, can travel at that speed.
It's impossible to accelerate any material object up to the speed
of light because it would take an infinite amount of energy to do
so.
2.What are the 3 common light frequencies used in fiber optics?
The three main wavelengths used for fiber optic transmission are
850, 1300, and 1550 nanometers. These wavelengths are used in fiber
optics because they have the lowest attenuation of the fiber.
