A series of waves with decreasing wavelength labeled radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays from left to right as wavelength decreases. At visible light is at a place with colored bands crossing the waves with dotted lines down to a colored spectrum from red to blue labeled in nanometers from 700 to 400. Above the waves are a label Frequency with an arrow pointing left labeled decreased and an arrow pointing right labeled increasing. Topmost is a label Wavelength (meters) with an arrow pointing left labeled longer and an arrow pointing right labeled shorter. Use the image to rank the colors from the color that will refract the least to the color that will refract the most. Least Most
