Because of the resolution of the colours as light reflects through the water particles

Why is rainbow formed in the sky in the shape of arc?
a rainbow is not shaped like a arc its a circle
Why are rainbows always in the same order?
The wavelength of coloured light varies. Red light is the lomger wavelength, and so appears on the outside(longer) side of the rainbow. Correspondingly, Blue light is the shorter wavelength, and so appears on the inside ( shorter) side of the rainbow. The colours in order are , (infra red ' not seen),red, orange, yellow., green, blue. violet and indigo , (ultra violet ; not seen). Also notice, that the light bends!!! Because outside the red arc the sky is darker., whilst on the inside of the blue arc the sky is lighter. If the rainbow is is particularly bright, then you will see a reflected rainbow, outside the primary rainbow. The colour order is reveresed. More rarely, you may see a triple rainbow, outside again. The colours a reversed back to their original order. The secondary bow is fainter than the primary bow and the triple bow is fainter again. Also when you seen a rainbow, stand with your back directly to the Sun. You are then looking at the centre of the rainbow. The coloured bow is at an angle of 42 degrees, from the direct line ,sun , you , and the rainbow centre. Finally, you may not see the full arc of the rainbow, this is because there is no rain falling from that part of the sky.
What is a multi-colored arc of light called?
rainbow
What are facts about about rainbows?
Hi a few facts A rainbow can be defined as a band of colours (from red on the inside to violet on the outside) assembled as an arc that is formed by reflection and refraction (or bending) of the sun's rays inside raindrops. They appear when it is raining in one part of the sky and sunny in another. Most people think the only colours of a rainbow are red, orange, yellow, green, blue, indigo, and violet, but a rainbow is actually made up of an entire continuum of colours, even colours the eye can't see! The idea that a pot of gold can be found at the rainbow's end originated somewhere in old Europe. In Silesia, an obscure area of Eastern Europe, it was said that the angels put the gold there and that only a nude man could obtain the prize. Can you go under a rainbow's arch and come out the other side? Not according to the laws of physics. A rainbow is all light and water. It is always in front of you while your back is to the sun. However, there is an old European belief that anyone passing beneath the rainbow would be transformed, man into woman, woman into man! Well, that would be less painful than going to a surgeon. When view from the ground, a rainbow appears as all or part of a great arc of colour. When viewed from a plane it is possible to see an entire circle as you can look down on raindrops as well as up to them.
What is the degrees of the sun when rainbow is formed?
When a rainbow is visible to you, the sun, your head, and the center of the rainbow's circular arc are all in a line. The sun must be in a clear sky, and the air in front of you must be filled with water droplets.
Why is violet on the bottom of the rainbow?
There are a couple of complicating factors in answering this question, so bear with me. First: a rainbow is actually a complete circle, or would be if the ground didn't get in the way. So instead of saying "bottom" and "top" let's talk about the inner arc and the outer arc. Second: the physics of refraction works out so that there are sometimes two rainbows; the outer one is considerably dimmer than the inner so it's often not noticeable. See the pictures on the Wikipedia rainbow page in Related Links for several examples. The secondary bow has the colors in reverse order. I'm only going to talk about the primary bow. Those caveats out of the way, the color on the inside of the primary bow ("bottom" at the highest point of the arc) is violet.
What is the first color of rainbow?
Starting from the outside: red, orange, yellow, green, blue, indigo, violet. Violet on the inside of the arc to Red on the outside and reversed on a double rainbow.
What is the innermost colour in the rainbow?
It is violet inside the arc and red outside.
Why is rainbow formed in the sky in the shape of arc?

What are the colors of the rainbow and how many colors?
Red, orange, yellow, green, blue, violet, indigo . Seven(7) colours. NB When observing a rainbow in the sky;- Red is always on the outside of the bow. Inigo(blue) is always on the inside of the bow. Outside the red arc, the sky is darker, (light bending) Inside the indigo arc, the sky is lighter, (light bending again). When observing a rainbow, the centre of the rainbow is in a direct line between the Sun(at your back), you and the rainbow centre. NNB The angle from the centre line of the rainbow to the arc is 42 degrees. NNNB A very bright rainbow will produce a reflected rainbow outside the primary rainbow; the colours are reversed.
What is a colorful arc?
A rainbow.
Why the colour sequence in the secondary rainbow is reverse in order?
In a "primary rainbow", the arc shows red on the outer part, and violet on the inner side. This rainbow is caused by light being refracted while entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, red facing toward the other one, in both rainbows. This second rainbow is caused by light reflecting twice inside water droplets.
