Why do they call a rainbow a "rainbow" when it doesn't have a bow on it?

Genesis 9:12-17: And God said to Noah, 'This is the token of the covenant which I make between me and you and every living creature that is with you , for perpetual generations:\n\n    I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth. \n\n    And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud:\n\n    And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh'.

Thats a simple science question.\nRainbows almost always appear during or right after a rainstorm. The water vapor in the air forms to act as a prism. With the right angles of sunlight in relation to the water vapor, the "prism" breaks the "white" or "ultraviolet" light up into it's true colors which are red, orange, yellow, blue violet and green. I always use to remember the primary colors by using the accronym, "roybug" changing the "u" to a "v" for the violet.

I won't give you a cut-paste answer, but this is my favourite rainbow explanation site:\nhttp://www.gryndlscot.com/rainbow.html

A rainbow is an optical and meteorological phenomenon that causes a nearly continuous spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere.

they are (called Johnathon Rainbow)

Why not teach on the first rainbow; in the story of Noah? The rainbow represents G-d's promise to never destroy the world again with a flood. Rainbows represent mercy.

Rainbows are caused when sunlight is bent as it passes through raindrops.  Different wavelengths of light (different colors) bend at slightly different angles, which separates the white light into its different colors.  Because there is a specific angle that each color bends, these colors will always be at a specific distance from the sun.  Next time you see a rainbow, you can notice that the sun is either at the center of the rainbow, or else the rainbow is centered at a point directly opposite the sun in the sky.

We can see two simultaneously rainbows sometimes. The first one is produced by one internal reflection inside the raindrop, and the second one is produced by two internal reflections.\nTheorically, light can reflect more times inside the raindrop, but I think nobody has seen a third rainbow.

Double rainbows are a rarity.\n\n\n\n\n \nThe Double Rainbow\n\n \n\n\nEvery once in a while, if you get lucky, you may see a second rainbow on the outside of the first, brighter rainbow. This is the "secondary rainbow" which occurs when raindrops high in the atmosphere refract and reflect light back to the viewer. \n\nThese raindrops are higher than those which cause the "primary rainbow" and are special because they internally reflect the incoming sunlight twice rather than just once. \n\n\n\nNotice that the sunlight hits the bottom of the raindrop to make the secondary rainbow. There is still sunlight hitting the other parts of the raindrop, however, some of the light is simply transmitted through the raindrop without reflecting, and some light is reflected and refracted, but not into our eyes: that light is for someone else's rainbow. \n\nNotice also in the image at the top of the page that the sequence of colors in the secondary rainbow is switched compared to the primary bow. Why is this? \n\n\n\n\n\n--------------------------------------------------------------------------------

Your perspective to the event, it is so large and you can only stand in on place at a time.  Hence why you can never find the end of the rainbow.

Never heard "rainbow sheep" in my life.  Who changed that?  Where'd you come up with this?\nAnd yeah, I definitely have to agree on that rainbow = gay thing.  If they wanted to change it to be "politically correct," maybe they should have changed it to plaid, or clear, or keep it true to the SHEEP....."FLUFFY!"\nThat's gotta be the most ridiculous thing I've ever heard, I swear.

What makes the bow?\nA question like this calls for a proper physical answer. We will discuss the formation of a rainbow by raindrops. It is a problem in optics that was first clearly discussed by Rene Descartes in 1637. An interesting historical account of this is to be found in Carl Boyer's book, The Rainbow From Myth to Mathematics. Descartes simplified the study of the rainbow by reducing it to a study of one water droplet and how it interacts with light falling upon it. \nHe writes:"Considering that this bow appears not only in the sky, but also in the air near us, whenever there are drops of water illuminated by the sun, as we can see in certain fountains, I readily decided that it arose only from the way in which the rays of light act on these drops and pass from them to our eyes. Further, knowing that the drops are round, as has been formerly proved, and seeing that whether they are larger or smaller, the appearance of the bow is not changed in any way, I had the idea of making a very large one, so that I could examine it better. \n\nDescarte describes how he held up a large sphere in the sunlight and looked at the sunlight reflected in it. He wrote "I found that if the sunlight came, for example, from the part of the sky which is marked AFZ  \n\nand my eye was at the point E, when I put the globe in position BCD, its part D appeared all red, and much more brilliant than the rest of it; and that whether I approached it or receded from it, or put it on my right or my left, or even turned it round about my head, provided that the line DE always made an angle of about forty-two degrees with the line EM, which we are to think of as drawn from the center of the sun to the eye, the part D appeared always similarly red; but that as soon as I made this angle DEM even a little larger, the red color disappeared; and if I made the angle a little smaller, the color did not disappear all at once, but divided itself first as if into two parts, less brilliant, and in which I could see yellow, blue, and other colors ... When I examined more particularly, in the globe BCD, what it was which made the part D appear red, I found that it was the rays of the sun which, coming from A to B, bend on entering the water at the point B, and to pass to C, where they are reflected to D, and bending there again as they pass out of the water, proceed to the point ". \n\nThis quotation illustrates how the shape of the rainbow is explained. To simplify the analysis, consider the path of a ray of monochromatic light through a single spherical raindrop. Imagine how light is refracted as it enters the raindrop, then how it is reflected by the internal, curved, mirror-like surface of the raindrop, and finally how it is refracted as it emerges from the drop. If we then apply the results for a single raindrop to a whole collection of raindrops in the sky, we can visualize the shape of the bow. \n\nThe traditional diagram to illustrate this is shown here as adapted from Humphreys, Physics of the Air.  It represents the path of one light ray incident on a water droplet from the direction SA. As the light beam enters the surface of the drop at A, it is bent (refracted) a little and strikes the inside wall of the drop at B, where it is reflected back to C. As it emerges from the drop it is refracted (bent) again into the direction CE. The angle D represents a measure of the deviation of the emergent ray from its original direction. Descartes calculated this deviation for a ray of red light to be about 180 - 42 or 138 degrees. \n\nThe ray drawn here is significant because it represents the ray that has the smallest angle of deviation of all the rays incident upon the raindrop. It is called the Descarte or rainbow ray and much of the sunlight as it is refracted and reflected through the raindrop is focused along this ray. Thus the reflected light is diffuse and weaker except near the direction of this rainbow ray. It is this concentration of ray

Why don't you search the answers to the previously posted questions here on this topic? This has been asked over and over. \n\nHere is a little bit to get you started:\n\nRainbows are caused because the different colors in white light are bent by different amounts in rain drops, so the colors get separated. The sun shines from behind the observer, and then bounces off the back surface of the raindrops, and those raindrops that are at the required position for light to reach the observer from the sun contribute to the rainbow. This arc is formed by the collection of raindrops which are at the vertices of angles of 42 degrees between the observer and the sun.

A rainbow is a prismatic effect, a kind of optical illusion, because of water droplets in the air and the way the sun shines through them.

http://eo.ucar.edu/rainbows/\n\nThe traditional description of the rainbow is that it is made up of seven colors - red, orange, yellow, green, blue, indigo, and violet. Actually, the rainbow is a whole continuum of colors from red to violet and even beyond the colors that the eye can see.\n\nSunlight is made up of the whole range of colors that the eye can detect. The range of sunlight colors, when combined, looks white to the eye. This property of sunlight was first demonstrated by Sir Isaac Newton in 1666. \nLight of different colors is refracted by different amounts when it passes from one medium (air, for example) into another (water or glass, for example

It is a second rainbow caused by the way light reflects inside of raindrops.  They will appear between 50 and 53 degrees above the horizon and the colors are inverted.  There is also a band of darker sky between the two, this is called an Alexander's band.
