What Are the Colors of the Rainbow in Order? Officially, the rainbow color order is as follows: Red Orange Yellow Green Blue Indigo Violet This means that every rainbow you see will have these seven colors in this order from the top of the arc of the rainbow to the bottom of the arc.

Looking for Graduate School Test Prep? We all know that light is made up of from the combination of different colors. If someone wants to know how a rainbow is formed, he should first know how a prism works because both of procedures are the same. In the prism, when white light enters from one side, then on the opposite side, it shows its reflection in the form of mini-rainbow. Same in the case of the rainbow, the raindrops will act as a prism. When the light enters in the raindrop, from the opposite side, it will also be reflected.
At this position, different angles are formed between the light that is coming in and the light that is coming out. Like in producing the violet color, the angle will be of 40 degrees. These angles will make the different colors and when you will see from your eyes, you can see different colors of the rainbow.
All these colors are the source to build the spectrum or a circular arc in the sky that appeals every human to enjoy nature. There is also a chance that you will see the double rainbow, the reason is that such types of droplets will have two types of reflection and hence, they will make a double rainbow in the sky where you will be able to see two rainbows at a sky at the same time. In the primary rainbow colors are always find in the particular pattern.
That always remains the same when it will appear in the sky. The order of the colors in a rainbow is as:. By reading this you will get the answers to the questions that what are the rainbow colors and what is their order.
From all these colors, Red has the greater wavelength. The pattern always remains the same in the primary rainbow because all the colors of the rainbow appear due to its wavelength. So the red always appears on the top because of its highest wavelength. All other colors with the shortest wavelength will appear far from it. After the rain, if there will be clouds in the sky and the high mountains in the area where you live, the rainbow will not appear and you will not see it with your eyes.
It will only appear in the areas where there is no obstacle or things to restrict the appearance of a rainbow. It is important that the sun should be quietly lower than its position. The sun should not also hide under the clouds because in the rainbow construction there is a great contribution to sunlight.
Some researchers have shown that the sun should be at 42 degrees from the horizon so it will be easy to build the rainbow and definitely, you will get more chances to see it after every rain.
Some of the colors in that mixture of white light are getting absorbed by the object, and other colors are getting reflected. Now the ones that reflected are the ones that get bounced back into our eyes, and then our brain says, uh-huh, this object is red. ERIC: That leads into another question we got, which is really important from both a fashion and a science perspective.
Why is it that sometimes two shades of black don't match each other? ZOE: Well, like we said, white light is a mixture of all of those different colors, it's a ton of light that's hitting your eyes all at once.
Black then is the opposite of that, it's like the absence of light. So if an object looks black, it's because it's absorbing most of the light, and not much is actually getting reflected back to your eyes.
Now, the blackest of all blacks, paints like Vantablack or black 3. Some of the black objects are reflecting reddish light, perhaps, some of them are reflecting just a little bit of yellowish light, some of them bluish. Because they might be reflecting slightly different types of light, they won't actually match.
Most of the time this doesn't matter because if you have something that's absorbing almost all of the light next to something that's reflecting almost all the light, black next to white, it doesn't really matter if the black is slightly red or not.
But if you put those two black things next to each other, the contrast becomes much more apparent. ERIC: So that leads into the next question we got, which is how many shades of a color are there, is it infinite? ZOE: Essentially, yes, if you look at those colors and if you think about those wavelengths of light or different amounts of energies, you could say, okay, red is nanometers.
Different shades of red could be nanometers, nanometers, and a half nanometers, etc. You could have all these infinite shades of red, and that's just talking about actual wavelengths.
If you really think about how Review colors, you can think of them as having different amounts of lightness and darkness, artists call that value.
You can also think about them having different amounts of saturation, in other words, how bright or dull is the color? And you can think about the colors having a certain temperature, which basically means does the color seem more warm or cold? Does it lean more towards red or blue? So if you take all of these different variables into account, you wind up with pretty much an infinite number of shades that can exist. However, our brains don't actually perceive every single one of those infinite shades.
We really only perceive a strict number of them, and it's still quite a lot, I was reading up on this and people were estimating that it's something like humans can perceive a good 10 million colors. ERIC: And our next question is about perhaps the most colourful thing in nature, rainbows, so when asked, how do they form?
ZOE: Yes, I do love a good rainbow. Rainbows are actually pretty interesting in the way that they're form, they're not really objects in themselves. They're more like optical illusions that are caused by the way that sunlight hits droplets of water in the air, so this might be rain, hence the name rainbows.
But it could also be spray from a waterfall or something, in that case they're technically called spray bows, and so on, you can have fog bows etc. And so what happens is the sunlight hits the water droplet.
Basically, it enters the water, bounces off the back of the water droplet, it reflects, and then it exits the droplet again. Essentially, this means that the sunlight has to be behind you while you're looking at a rainbow. Because if the sunlight is behind you, it can hit those water droplets, reflect off the back of the droplet and come back to your eyes.
ZOE: Right, now, the reason that we see all of those colors is because when the light enters and exits the water droplet, it does what we call refraction. Which basically means that when light enters a different medium, it will bend.
The different colors, the different energies of light, they bend different amounts. So the red light bends a little bit, the blue light bends a lot, that kind of thing, and that causes the colors to spread out.
