What is a white light spectrum?

A white light spectrum is the range of colors produced when white light is dispersed, typically through a prism. It consists of a continuum of wavelengths, including red, orange, yellow, green, blue, indigo, and violet, commonly remembered by the acronym ROYGBIV. Each color corresponds to a different wavelength of light, with red having the longest wavelength and violet the shortest. This spectrum demonstrates that white light is composed of multiple colors, which can be separated and recombined.
