Isaac Newton Explains The Big Misconception About LIGHT
This topic addresses the massive paradigm shift Newton caused regarding optics. Before Newton, the prevailing scientific consensus (dating back to Aristotle) was that white light was "pure" and that colors were created by modifying or corrupting white light (e.g., passing it through glass "stained" it). The script should detail Newton’s "Experimentum Crucis" (Crucial Experiment) where he isolated a beam of sunlight with a prism, then took a specific color (like red) and passed it through a second prism.
If the old theory were true, the red light should have changed again. It didn't. It stayed red. This proved that white light isn't pure; it is a composite of all colors combined. This was a reality-shattering realization at the time. The video should also touch on his "Corpuscular Theory"—that light is made of particles, not waves—and how he had to essentially stick a bodkin (a large needle) behind his own eye to experiment with how pressure affects color perception. It frames the "misconception" as the idea that what we see (white light) is fundamental, when it is actually a complex illusion of mixtures.
