This is hardly a significant photograph, but I just have to show it to you. I went cycling yesterday under impossibly blue skies from the horizon to the zenith. When I stopped to rest at the end of my ride at the harbor, I was just marveling at how clear and blue the sky was. Just drinking in the color was a sublime experience. So that's why I am simply showing the sky to you, instead of giving you a more complex photograph.
Why is the sky blue?
ReplyDeleteEasy. Because when the white light from the sun passes through our atmosphere, the longer wavelength red light passes through the air molecules undisturbed. The shorter, blue wavelengths, however, are scattered by the air molecules. This scattered blue light is what makes the sky blue. I think...
ReplyDeleteWhy is the water blue?
ReplyDeleteThe water is not blue. The water *looks* blue because it reflects the sky.
ReplyDelete"Ask Mr. Wizard." Wasn't that a TV show in the 50's or 60's?
ReplyDeleteYou could fill that role easily!
