Light and Color Concepts

The video tutorial explores the concept of visible light, using rainbows as an example. It explains that visible light is a narrow range of wavelengths within the electromagnetic spectrum, situated between infrared and ultraviolet waves. The tutorial discusses white light, which comprises all visible wavelengths, and how it can be split into different colors using a prism. Sir Isaac Newton's work on light and color is highlighted, along with the mnemonic ROYGBIV for remembering the colors of the spectrum. The video also covers the properties of pure colors and the relationship between wavelength, frequency, and photon energy. It concludes with a reminder of the importance of kindness.
