Hehe, well if you really want to bother about the sunset, here it goes:
Miraculously, red/blue shift phenomenon has nothing to do with the reddish sky color during sunrise/sunset. If that was the only effect that caused the color shift of the sky then nobody would notice it at all. The effect is clearly visible only at near-light speeds, while the earth surface is rotating only at about 462.8m/s.
Now, during daytime, as sunlight passes through the atmosphere, the blue and violet light gets dispersed throughout the sky, while the longer wavelenght light passess through. That's why the sun looks yellow from earth, while it's kinda white-ish from space. Now, when it comes to sunrise/sunset, the sun is striking the earth at an angle, and the amount of atmosphere through which sunlight has to pass increases. That causes the light of lower frequencies (yellow and red to some extent) to become dissipated as well. The color of the sky becomes more yellowish, and the sun becomes reddish, as red is the only component of light that is still largely unaffected by the atmosphere. |
REFRACTION!
hehe, just like i said, you can forget the whole blueshift / redshift thing then
