Background Information. The different colors of visible light have different wavelengths. Violet light has the. shortest wavelength, has the most energy, and is closest to ultraviolet light. Red light has the. longest wavelength, has less energy, and is closest to infrared light. The other colors of visible. light increase in wavelength and decrease in energy as they get closer to red and infrared light. When you shine white light or sunlight on a colored object, the object will appear to be.
