HISTORY OF FIBER OPTICS * In 1840‚ Daniel Colladon and Jacques Babinet demonstrated the principle of guiding light by refraction. * It was followed by a public demonstration by John Tyndal in 1852. In 1870‚ Tyndal wrote about the property of total internal reflection in his book about the nature of light. * In 1880‚ Alexander Graham Bell and Sumner Tainter invented the Photophone‚ a device capable of transmitting sound waves over beam of light. This is considered as mankind’s first attempt

ABSTRACT: Water is omnipresent in foodstuffs and the surrounding atmosphere. In principle‚ the moisture content of a food can therefore be determined accurately by measuring the number or mass of water molecules present in a known mass of sample. It is not possible to directly measure the number of water molecules present in a sample because of the huge number of molecules involved. A number of analytical techniques commonly used to determine the moisture content of foods are based on determinations
