White light is a combination of all colors of visible light. When light passes through a prism, it separates into a spectrum of colors, including red, orange, yellow, green, blue, indigo, and violet. This phenomenon demonstrates that white light is not a single color but rather a mixture of many wavelengths. In nature, white light is most commonly associated with the Sun. The sunlight appears white when viewed from space, but it can appear yellowish or reddish when it passes through the Earth's atmosphere. This scattering of light is why we see different colors during sunrise and sunset.
