White light is which of the following?

White light is which of the following?

• A. A Single Spectral Color
• B. Darkness
• C. A Form of Ultraviolet Light
• D. The Combination of All the Spectral Colors

Answer: (D)

White light is made up of all wavelengths of visible light. When white light passes through a prism, it is separated into a spectrum of colors, showing that white contains many colors blended together. Darkness is the absence of light, so it isn’t white. Ultraviolet light lies beyond the visible range, so white light isn’t ultraviolet. A single spectral color is just one part of the spectrum, not white. In everyday sources like the sun or a white light bulb, white results from mixing multiple colors of light, an additive process. So white light is the combination of all the spectral colors.
