Rebecca was deciding what color to paint her room. She was deciding between sky blue, sea green, or canary yellow. While thinking about which color would be best, she wondered why things had color at all, such as the sky being blue. What makes the sky appear to be blue? A. Only blue light can pass through the atmosphere without hitting particles. B. The particles in the atmosphere are naturally blue. C. Only blue light is absorbed by the particles in the atmosphere. D. Only blue light is reflected by the particles in the atmosphere.

The clear sky appears as blue due to Only one correct answerA.Reflection of lightB.Atmospheric refractionC.Scattering of lightD.Absorption of light

Water appears blue because shorter visible wavelengths (blue) are absorbed more than  longer visible wavelengths (green and red) and near-IR radiation. FalseTrue
