Theory of relativity is related to light given by the Great Scientist Albert Einstein. In march 1905, Albert Einstein, one of the greatest scientific minds of all time explained the quantum Theory of light. According to this theory , light exists as tiny packets or particles which is called photons. Along with another scientist, max Planck, Einstein proposed one of the most revolutionary ideas in twentieth century physics that we live in a universe built out of tiny, discrete chunks of energy and matter.
Later in 1905 he published his theory of special relativity. In this theory he extended Galileo’s principle of relativity, so that it accounted for the constant speed of light Einstein saw light as both a wave and a particle. He showed that nothing can move faster than light in a vacuum and that the speed of light in a vacuum is always the same. His work revolutionized the way scientists viewed the world and had a tremendous impact in the field of physics especially in studies light.
