= Why is The Sky Blue? =

Light passes through clear fluid and suspense small particles. Blue has a very small wavelength and scatter stronger then red. This is called the Tyndall effect that because it was discovered by John Tyndall in 1859. It is also called Rayleigh scattering after Lord Rayleigh. He proved that the amount of light scattered is inversely proportional to the fourth power of wavelength.  When the light hits the water and scatters the color. During midday we would be at the angle the shows blue and at dusk we are in the perspective of red

Interesting Fact:  Sunsets look red because the blue light is out of our line of sight on the earth.
