Fiber

Glass is the greatest reflector made by man. At  this time it can be heat at a fixed temperature. For this it needs sufficient energy. The name of the energy is `LASER`. The another advantage of the Laser is that it can use as the optical ray, the capacitor of heat energy and signal at the same time. The most significant quality of the glass is that it increases its length in accordance with melting it. Keeping this truth in front of us the scientists have invented “Optical fiber”. At first the glass is turn into vapor by applying heat. Then the vapor is frozen pouring into a thin and very cold pot. The scientists in the have become able to make a 10 miles long glass road from 1 kg glass shred. At last many fires are made about 1/1000 inches thick melting and twisting this rod.
