Light and Color - Mission LC Detailed Help

White is not really a color. Rather, white can be considered to be ____.

Visible Light
Light is a form of electromagnetic (EM) radiation. The human eye is sensitive to a narrow range of frequencies within the enormous range that the EM spectrum spans. Visible light itself is a spectrum of frequencies that is often referred to as ROYGBIV. Objects that appear white are reflecting visible light. The whiteness of such light is most often attributed to the presence of all the frequencies of the visible light. ROYGBIV, when present together, results in white light.
