What Makes the Sky Blue

   The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air. However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

                          Above me an eagle spreads his wings to claim dominance of the sky.

    Water is blue partially because the sky is blue. Since the sky creates so much blue light, a lot of this light is reflected off the surface of the water. We are all aware that we can see ourselves in still bodies of water. This mirror action also works for the sky itself, giving water a blue hue.

    I live on an island and no matter the direction you drive you will eventually come to the water. The water and the sky are the big canvas's in my world on which blue is painted every day.
