White light is a mixture of all colors of visible light combined. It can be produced by various sources, such as the Sun, light bulbs, and LEDs. When white light passes through a prism, it separates into the colors of the rainbow, demonstrating its composite nature. In physics, white light is often described in terms of its wavelength, with each color corresponding to a specific range. The visible spectrum includes colors like red, orange, yellow, green, blue, and violet. Understanding white light is essential in fields like optics and photography, where light manipulation is crucial.
