How is light duscovered ?

Aristotle was responsible for one of the first theories of light. He stated that, “The essence of light is white light. Colors are made up of a mixture of lightness and darkness.” However, It was Sir Isaac Newton who conducted several experiments to understand light. As the temperature increases, more atoms collide with other atoms such as to drive electrons to jump to a higher energy levels, and emit light as they fall back into lower energy levels. ... Light can also be produced by nuclear reactions, such as fission and fusion. Light is electromagnetic radiation that shows properties of both waves and particles. Light exists in tiny energy packets called photons. Each wave has a wavelength or frequency. ... In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.
