Bill Nye: The Science of Light and Color

Bill Nye explores the science of light and color, explaining how white light is a combination of all colors. He demonstrates how prisms separate light into a spectrum and how mixing primary colors can create new colors. The video also covers how colors are perceived in nature, the technology behind neon lights and lasers, and why the sky appears blue. The episode concludes with a recap of the key concepts discussed.
