White light is made of which of the following?

White light is made up of a range of colors, which can be observed when light passes through a prism. This phenomenon, known as dispersion, shows that white light is actually a mixture of various wavelengths of light, corresponding to different colors of the visible spectrum, including red, orange, yellow, green, blue, indigo, and violet.

When white light is refracted, it separates into these colors, demonstrating its composite nature. This characteristic is fundamental in understanding how light interacts with objects and materials and is pivotal in concepts such as rainbows and color mixing. Recognizing that white light contains multiple colors rather than just one or a limited combination is crucial in studies of optics and vision.
