Optical fibre : a  luminous discovery Science has given us many valuable and useful things, we know them as Inventions. Similarly, Optical fibre is also a scientific invention.......... We know about bulb , tube light. we take about bulbs we immediately remember that one name is Thomas Edison . This is an important and enlightening invention or discovery of everyones  life. But bulb can give you light up to a limited area. There was limit to the light........ But light has no limits this is what we see in optical fibre in physics. Let's start with basic information about optical fibre. In Marathi, it can be called as 'प्रकाशिय तंतु' ( light fibre.)   Descovery of optical fibre  It was discovered in 1952, Imperial College, London. The inventor of optical fibre is Narinder Singh Kapany  is Indian but had gone to Imperial College, London for higher education. He made glass string while doing his research work. The peculiarity of this glass string is that when a lamp was lit

Work, energy and power are the basic and important concept of Physics. In short physics is incomplete without the terms Work , Energy and Power. Work, Energy and Power are interconnected properties because in simple language Enargy means 'the ability to do Work.' We known about this concept from the 8th or 9th class.  Work, energy and power are the basic concepts of physics but this are very important and intrasting concept.  Work means effort, parform, function .... Energy means spirit, power. Energy ~ Work ~ Power  Energy is everywhere around us but we can't see this, only we can feel the energy in different forms.  Examples :- in kitchen for cooking food we use heat is nothing but one of the form of energy is known as heat energy. Similarly for car driving, jumping, in festival we use cracker , all have electricity in our home is also type of energy....etc  Energy is available in various forms or formats in the nature. First we start with the main domain of physics for
