Which sentence from the article BEST explains how the color of the sky is affected by the way light moves?
The light that people see with their eyes is just one tiny bit of all the kinds of light energy in the universe.
Like energy passing through the ocean, light energy travels in waves, too.
Blue is scattered more than other colors because it travels as shorter, smaller waves.
Closer to the horizon, the sky fades to a lighter blue or white.
