| | | Light | | | | | Light is the source of “life”. Light is nothing but energy that creates and sustains life in all its varied colours and forms. Most beautiful things like rainbow, twinkling stars, sparkling in the still water of lakes, roses and tulips, fall colours and our pictures are all the ways in which ”light” expresses itself. We explore the expanding universe through telescope to understand the hows and whys of everything around. |  | | Sir Issac Newton himself who discovered that white light is a combination of many colored lights. James Clerk Maxwell's brilliant unification of optics and electromagnetism, gave birth to many fields of Engineering. Albert Einstein, invented Photo–Electric effect that won him his noble prize. His equation combining Energy with the speed of light is perhaps one of the most famous equations in physics. | | | Light has an equally important sway in contemporary technologies. Today's communication systems are getting better every day with the application of Fiber optics. Today's manufacturing is revolutionized by the LASERs, another advanced application of light. In the ensuing topics, you will learn all the fundamental concepts of light that helps you explore all these fascinating phenomenon at depth. | | |
