Sir Isaac Newton famously used a glass prism in his experiments to demonstrate what key discovery about the nature of light?

Explanation

Sir Isaac Newton famously used a glass prism in a series of experiments during the seventeenth century to demonstrate that ordinary white sunlight is actually composed of a full range of different colors, which the prism separates through refraction into the familiar visible spectrum. Newton further showed that this separated colored light could be recombined back into white light using a second prism, reinforcing his conclusion that the individual colors were genuinely components of white light rather than something added by the prism itself. This influential work laid important early groundwork for the broader scientific field of optics. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
