RE: Scattered Showers Abound - August 14th 2018
Everyone looks very nice to look at the blue sky. How to open the sky so that the mind is good. Well, that we see the blue sky, we talk about the blue sky - what have you ever thought, why the sky is blue? Why is not any other color
Yes actually, I know exactly why it is blue and not any other color. It is in fact due to a process called Rayleigh Scattering, wherein the visible wavelengths with higher energies, I.e., the shorter wavelengths are scattered more readily by the molecules of air in the atmosphere... visible light wavelength of purple is scattered way up in the upper atmosphere so no purple enters the retina of humans.. but blue light wavelengths is just right so as to scatter alll about in the atmosphere by the molecules of air, and enter our retina as blue and not white.
Same concept as to why Sunsets appear red and orange. More atmosphere for the light to travel thru means longer wavelengths can eventually be scattered by the air molecules and enter our retinas.
