Final answer:
It is true that Newton demonstrated white light is made up of all the visible colors using a prism. This groundbreaking experiment led to the development of the field of optics.
Step-by-step explanation:
True, by passing a beam of sunlight through a prism, Newton showed that white light is comprised of all the visible colors of the spectrum. In his experiment conducted in 1672, which he described in a paper submitted to the Royal Society, Newton allowed sunlight to pass through a small hole and then through a prism, revealing a continuous spectrum of colors, from violet to red. This discovery was significant at the time and laid the foundation for understanding the nature of light and the science of optics.
