Why do they always appear in the same order on a rainbow in the sky?

A rainbow is a natural prismatic phenom. White light, containing all colors, strikes water particles in mid-air. Just like with a prism, the light must pass thru the moisture and as it does, the light is broken down into it's different wavelengths. They are represented in order of speed from which they pass thru the moisture. The wavelengths and speed at which each respective color of light passes thru the moisture does not change, so therefore, every rainbow is always comprised of the same colors and displayed in the same order.

Why does a Rainbow appear to be bent in a semicircle way?
Because at every point IN the rainbow, the angle between the direction to the sun and the direction to your eye has to be the same angle. The only bunch of points that can satisfy that requirement is a bunch of points that are all on the same circle.

How can you be looking at a rainbow and have someone else be looking at a rainbow and it is a different rainbow?
Everyone sees their own rainbow. The sun reflects off of a raindrop. The rainbow you see may be reflecting off a different raindrop than your neighbor. ========================= The exact center of the rainbow you see is always on the far end of a line from the center of the sun through your head. Nobody else's head can be exactly on that same line.
What direction do rainbows appear most of the time?
With your back to the Sun, you will see the full arc of a rainbow. An imaginary line from the Sun , through you, will take you to the centre of the rainbow. From that line to the centre of the rainbow, to the coloured arc is an angle of 42 degrees. The primary rainbow's colours, from the outside are rea, orange, yellow, green, blue violet, indigo to the inside of the rainbow. Since red light has a longer wavelength than blue light, then the red arc is longer , on the outside of the r'bow. Conversely the blue light is a shorter wavelength so it is seen on the inside/shorter side of the bow. If the light is very strong/bright, then you ,may see a secondary rainbow out side the primary rainbow. The colours are reversed in the secondary rainbow. Very rarely you may see tertiary rainbow, outside the secondary rainbow and the colours are reversed again. Also because of natural bending of light the outside of the red edge is dark and the inside of the blue edge is light. You only see a rainbow if rain is falling and the sun is shining in different part of the sky. The old weather lore in England, A rainbow in the morning foretells bad weather, the day. A rainbow in the evening and the bad weather is going away for the rest of the day. In fact it is more reliable than Red Sun morning or evening.
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.
Does the amount of moisture in the air affects the order of the colors in a rainbow?
No, the colors are always in the same order.
In which order do the colours of the rainbow appear when you see them through a prism?
The same as in a rainbow - red, orange, yellow, green, blue, indigo, violet.
Why do you think a rainbow is always the same order of colors?
It goes in order from highest frequency beam, violet, to lowest frequency, red.
Why is the order of the 7 colors of a rainbow always the same?
The amount by which light is bent depends on its wavelength. The colors are arranged in the order of their wavelengths.
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 a rainbow always the same size for the height and distance between the feet of the rainbow?
rainbows can be different sizes and height as each rainbow that is formed
Are the colors of the rainbow always in the same order?
yes.the rainbow is formed by water droplets acting as a prism, and the prism shows the color spectrum in ORDER And you can get what's called a double rainbow. In that, the order of colors in the outer arc will be reversed. The colours in order are, Red, Orange, Yellow, Green, Blue, Indigo and Violet. :)
Why the sun and rainbow can't see at same time?
There is no "why" because the hypothesis of the question is false.You absolutely can see the sun and a rainbow at the same time. In fact,if the sun isn't there, in a patch of clear sky, then there can't be a rainbow.Maybe the reason for your impression that you can't see them at the same timeis the simple fact that the sun and the rainbow are always in exactly oppositedirections from you, and so in order to see one of them, you must look awayfrom the other one.
Why always rainbow appears in curve shape not in straight line?
Because the angle formed by a line(from the sun) --> (to any point on the rainbow) and then --> (to your eye),is always the same angle, for any point on the rainbow.The only way that can happen is if the rainbow looks to you like a part of a circle.
Why does a Rainbow appear to be bent in a semicircle way?
Because at every point IN the rainbow, the angle between the direction to the sun and the direction to your eye has to be the same angle. The only bunch of points that can satisfy that requirement is a bunch of points that are all on the same circle.
What angle do you have to be at to see a rainbow?
One doesn't have to be at any specific angle to see a rainbow. What is Dependent on seeing the rainbow is the location of the rain, and sun relative to you. The sun is always behind a rainbow when seen. So you would be in front of the rainbow, rain, and the sun. Also, No two people see the same rainbow unless a picture or video was taken of the rainbow.
Will quartz always have the same crystal structure?
The crystal lattice will always be the same, but the crystal may appear in many different forms (habits).
