| [slm] Taken from: http://www.exploratorium.edu/snacks/blue_sky.html BTW, I love science soo much, mashallah The sun produces white light, which is made up of light of all colors: red, orange, yellow, green, blue, indigo, violet. Light is a wave, and each of these colors corresponds to a different frequency, and therefore wavelength, of light. The colors in the rainbow spectrum are arranged according to their frequency: violet, indigo, and blue light have a higher frequency than red, orange, and yellow light. When the white light from the sun shines through the earth's atmosphere, it collides with gas molecules. These molecules scatter the light. The shorter the wavelength of light, the more it is scattered by the atmosphere. Because it has a shorter wavelength, blue light is scattered ten times more than red light. Blue light also has a frequency that is closer to the resonant frequency of atoms than that of red light. That is, if the electrons bound to air molecules are pushed, they will oscillate with a natural frequency that is even higher than the frequency of blue light. Blua light pushes on the electrons with a frequency that is closer to their natural resonant frequency than that of red light. This causes the blue light to be reradiated out in all directions, in a process called scattering. The red light that is not scattered continues on in its original direction. When you look up in the sky, the scattered blue light is the light that you see. Why does the setting sun look reddish orange? When the sun is on the horizon, its light takes a longer path through the atmosphere to your eyes than when the sun is directly overhead. By the time the light of the setting sun reaches your eyes, most of the blue light has been scattered out. The light you finally see is reddish orange, the color of white light minus blue. Violet light has an even shorter wavelength than blue light: It scatters even more than blue light does. So why isn't the sky violet? Because there is just not enough of it. The sun puts out much more blue light than violet light, so most of the scattered light in the sky is blue. [wlm] :-) |

| [wlm] I used to think this when i was a kid: The sky is blue because the oceans are blue. The blue sky reflects the water. :-/ made sense to me! :-/ |

| [slm] I don't know WHY - i guess only Allah (swt) does, but i find it to be a very relaxing colour. [wlm] :-) |

| [slm] Medo, I think this poor chap :( must be suffering from cyanosis, defined as a bluish discoloration of the skin brought about by a lack of oxygenated blood. It can be the result of many conditions such as Raynaud's Phenomena, Congestive heart failure, lung disease, asthma, apoxia, toxins, or abnormal hemoglobin as in the case of methemoglobinemia.

| [slm] The blue sky is'nt sad :D. It makes people happy to look at it :) It only gets gloomy when it is cloudy ::) The best cure for depression is to take a walk away from all the roads and buildings, in a nice park or somewheres. In other words "take a hike" and enjoy nature. Maybe even do some moutain biking. You could survive as long as you have more experience than Bush (Who ended up sailing over the handle bars of his $3k somethin MB);D Anyways that's me 2D*. *D=penny ;) [slm] A Typical Mozlem that these Americans encounter now and then. |
