Isaac Newton
Isaac Newton is generally regarded as one of the greatest and most famous scientists in history. Newton was an astronomer, physicist, mathematic and philosopher who is known for theorizing and reporting on gravitational force and three laws of motion.
Isaac Newton discovered that white light is made up of a spectrum of colours, that when blender together produce the white light. He showed by use of a prism that white light can be split into a spectrum of colours and then used a second prism to show this spectrum can then be rejoined to produce white light. Newton also theorized that light was composed of particles but had to associate the property of light with waves in order to explain refraction of light.
