The correct answer is (C) Isaac Newton. Sir Isaac Newton was the first scientist to use a glass prism to split sunlight into its constituent colors, demonstrating that white light is a spectrum of colors.
Newton’s experiments with prisms laid the foundation for the understanding of the dispersion of light and the nature of color.
