Color

In 1666, Isaac Newton's prism experiment revealed that white light is composed of various colors. Light behaves as a wave, reflecting or refracting when encountering new media. The degree of refraction depends on wavelength, with violet refracting the most and red the least. Colors are perceived by the brain as different wavelengths of visible light. Rainbows form when raindrops disperse light like a prism. Materials interact with light based on their properties, with black absorbing all wavelengths and white reflecting them. The color of objects is determined by the wavelengths they reflect, with red objects reflecting red wavelengths. The world appears colorful due to the brain's interpretation of light wavelengths.
