I'm uneducated about this, and my answer may be completely wrong. Logically, however, I would guess that it is due to the speed of both the rotation and the sidereal motion of the earth. For a few moments, the sun's rays pass through and refract towards the observer at the proper angle to view a rainbow. Of course, this is given the atmospheric conditions are conducive to the rainbow itself. Therefore, one must factor in the movement and density of the moisture and wind in the atmosphere. The speed of rotation of the earth is about 1,001 mph and the sidreal speed is about 6,700 mph. The rainbow appears and fades as the optimum angle for the viewer given the atmospheric conditions passes. This brings to my mind a curious question: do rainbows appear on other planets, and if so, what atmospheric conditions allow them? For example, Venus has a thick cloud layer-is it then possible that one might observe a rainbow or something like it, if one were to stand on that planet? And, what about auroras, which are caused by solar emissions passing through the magnetic sphere of the earth?

Do rainbows appear in the same place on different days?

If you are in the same place, the rainbow will always appear in the same place because it all has to do with the angle you are at in relation to the sun (42 degrees - see the related link). So if you are always in the same spot (e.g. at your desk at work), the sun will be coming from the same same angle, creating the rainbow in the same spot. My understanding of what I've read, you'll only see a rainbow in a certain place in the sky from the same spot at a certain time of the year because the sun moves depending on the season. Also, it is not only the angle of the sun but also the height of it that has to be the same.


Is there a end to a rainbow?

No there is Not. Fact: A rainbow is just one big circle. My mother works for American Airlines, we were flying to Orlando, Florida and we flew through one. So no there is NOT a end to a rainbow.


What is a rainbow What particles is it made of?

A rainbow is caused from light scattered by raindrops. Sunlight is composed of many different colors, each with its own wavelength, meaning each color diffracts at a different angle causing the different colors of the rainbow. A rainbow is an optical phenomena - so it is not made of particles.

Why isn't there a rainbow during most rain storms?

There are a few reasons why a rainbow may not be seen after a storm. If there are clouds blocking the sunlight, no rainbow will appear. Additionally, your location may interfere with your ability to see a rainbow because a rainbow is only viewable from certain angles. While it might be raining on you there may not enough humidity in the surrounding area to make a rainbow appear. Where I live (West Texas) we get rain but it may be so dry in the surrounding area that no rainbow appears.
