Rainbows
Rainbows are an optical phenomenon that can be seen in the sky when the sun reflects off the water droplets from rain or the mist of a waterfall. This causes a spectrum of light known as a rainbow. Questions about rainbows can be directed here.

When was the rainbow first discovered?
The phenomenon of the rainbow has been observed for thousands of years, with ancient civilizations, including the Greeks and Egyptians, recording their observations. However, the scientific understanding of rainbows began to take shape in the 17th century, particularly with the work of Sir Isaac Newton, who demonstrated that white light could be dispersed into a spectrum of colors using a prism. Thus, while rainbows have been seen throughout human history, their scientific explanation was established in the early modern period.
Why the rainbow is in the shape of arc?
A rainbow is an optical and meteorological phenomenon that is caused by reflection of light in water droplets. The rainbow is a circle with the anti-solar point in the middle (the shadow of your eye or the camera capturing the rainbow). The circle of the primary rainbow has a specific angular width of 42° from the anti -solar point.
The rainbow is not located at a specific distance, but comes from any water droplets viewed from a certain angle relative to the Sun's rays. Thus, a rainbow is not a physical object, and cannot be physically approached. Indeed, it is impossible for an observer to manoeuvre to see any rainbow from water droplets at any angle other than the customary one of 42 degrees from the direction opposite the Sun. If you use a garden hose to spray droplets when it is sunny out you can see the entire ring and indeed from airplanes and cliff edges I have seen almost entire circles from rain.
How many rainbow have been see at the same time?
I have seen 3 my friend up in northern Sweden claims 5.
they mean that God wont flood the earth again like it says in The Bible and Torah.
A rainbow means good luck and a way God can communicate saying he wont flood
the world.
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.
Is it possible to have inverted rainbow?
Yes, inverted rainbows, also known as supernumerary rainbows, can occur under specific conditions. These phenomena happen when light is refracted through water droplets in a way that creates additional, fainter arcs inside a primary rainbow, often appearing above it. While true "inverted" rainbows (with colors reversed) are not possible, the visual effect can create the illusion of an inverted arrangement. However, the classic rainbow order (red on the outside, violet on the inside) remains unchanged.
What happens when you go under a rainbow?
Nothing in particular, mainly because that's not possible. The center of the rainbow always
appears in front of you, directly opposite the sun. When you move, the rainbow moves.
When is purple in the rainbow?
The 7 classic colors are red, orange, yellow, green, blue, indigo, and violet (purple).
(Richard Of York Gave Battle In Vain.)
However the diffraction provides shades of many colors. Every color imaginable, named and not named, every color that the eye can perceive, is in the rainbow.
The basic colors in order are:
- Violet
- Indigo
- Blue
- Green
- Yellow
- Orange
- Red
ROY G BIV
Red, Orange, yellow, green, blue, indigo, violet
Although a rainbow should have every single color if the light being shined is truly white
There are seven colors of the rainbow which can be remembered by just using one key word. This word in ROYGBIV which is an acronym for the seven colors. ROYGBIV stands for Red, Orange, Yellow, Green, Blue, Indigo and Violet. You will notice that each color sits next to a color that is similar to it such as red then orange then yellow. Mixing paint that is red and yellow will give you a n orange color and is one proven way of showing the changes of color in a spectrum.
red, orange, yellow, green, blue, purple, & violet
You can remember them this way:
Richard of york gave battle in vain - the first letters of each word are the first letters of each colour.
Why does the rainbow arranged in roygbiv?
That's the sequence of the colors of light in order
from longest to shortest wavelengths.
How does light and rain make a rainbow?
The moisture droplets in the air refract the light like a prism. This happens with millions of droplets, and depending on the angle at which you observe it, you see a rainbow.
Split you computer screen into 3 sections:
1. nyan.cat (its a website)
2. Rainbow Unicorn Attack (RUA)
3. tecno kitty (on youtube)
Start to play RUA at the same time as watching the other 2.
Do this for more than 10 min and barf a rainbow.
No one made the rainbows. Rainbows are a naturally occurring phenomenon.
What em waves are used in rainbows?
Rainbows are formed when sunlight, which is a combination of various electromagnetic (EM) waves, interacts with water droplets in the atmosphere. The sunlight is refracted, reflected, and dispersed, resulting in the separation of different wavelengths of light, which correspond to different colors. The visible spectrum of light, ranging from red to violet, is what we see as a rainbow. Thus, the EM waves involved in the formation of rainbows primarily include visible light waves.
What are the six colors of the rainbow?
There are actually seven colours in the rainbow. They are : red, orange, yellow, green, blue, indigo and violet.
Do air disperse sunlight to prodce a rainbow?
No. Water droplets in the air act as tiny prisms. When the Sun hits them, light is reflected back to your eyes, but since the water droplets are not flat, the different colors of sunlight are spread apart just enough to see them separately. We often call this a 'Rainbow'.
