What did Newton demonstrate by his experiments with the prism?
Newton demonstrated the phenomenon of "dispersion of light" by his experiments with the prism. He showed that white light is in fact composed of seven colours: red, orange, yellow, green, blue, indigo, and violet.
Explanation
In 1665, Sir Isaac Newton discovered through his experiments that if a beam of white light (like sunlight) is passed through a triangular glass prism, the white light splits to form a band of seven colours on a white screen, which is known as the spectrum of white light.
