Albert Einstein 23 - Einstein's Revolutionary Paper

For over two centuries, Scientists had regarded light as waves. Albert's scientific paper ‘On a Heuristic point of view concerning The production and transformation of light' That dealt with Quantum Hypothesis Laid the foundation of new physics - The Quantum theory. This was a very significant paper that Pointed and established light As a collection of particles - ‘Light Quanta' and not waves. There is more to light than The colours we perceive! Visible light is called ‘Electromagnetic Radiation.' Red light has the lowest energy and The longest wave length of all visible light. ‘Infrared waves' are invisible with lower energy. TV's remote control would be a good example. The shorter wavelengths below the Infrared waves Are the ‘Microwaves' which can heat and cook food By making the water molecules in it, vibrate rapidly. At longer wavelengths there are ‘Radio waves, Which transmit radio signals. ‘All the above light waves theories were established By scientists of the earlier centuries. It was the higher end of spectrum That caused problems for physicists in1800's. At energies higher than violet light, There is ‘Ultraviolet light' or UV radiation. The particles of ultraviolet light hit the surface of a metal Causing an electric current to flow. This is the Ultraviolet photoelectric effect. He also showed that the size of the current Does not depend on the intensity of light, Shining on to the metal.' Einstein's paper on the photoelectric effect Compared radiation to a gas. He came up with light quantum hypothesis: "Radiation behaves like energy quanta of energy E=hf." Though it took few well-known physicists To discuss, debate, experiment, On Einstein's Quantum theory, The end result was success -over a period of time. Most of the scientists conceded and bowed down To Einstein's super research and reasoning. He was hailed as a genius by the physicists And applauded for his classic logical conclusion.
