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.

How many colors are in a rainbow?

Answer #1:

The main colors are:

Red

Orange

Yellow

Green

Blue or Indigo

Violet (not purple)

There are seven colors in the rainbow and can be remembered by the mnemonic device Roy G. Biv: Red, Orange, Yellow, Green, Blue, Indigo and Violet.

An easier way of remembering the seven colours of the rainbow is by this expression: "Richard Of York Gave Battle In Vain."

However, indigo is not considered a part of the color spectrum. That was added because an early researcher assumed there were 7 different natural colors like there are 7 different music notes in a key.

========================================

Answer #2:

The rainbow has ALL of the colors ... every color of cloth, paint, hair, paper, stone, or animal that ever existed. Every color that the any eye has ever seen, or CAN see, is in the rainbow. There are millions of them. Many have names, but most don't.

How do rainbows form?

Sunlight is made up of the colours of the rainbow, though we don't normally see the separate colours. When sunlight passes through raindrops in the sky, the raindrops can act like a clear glass prism. This prism effect splits the sunlight into the colours we see in a rainbow.

Can rainbows occur in the winter?

Yes they can. I live in Canada and it is winter time. I have seen about 5 rainbows in the last 3 weeks, and the sky is always clear or cloudy, no rain or snow. From what I have found online they are quite rare but they seem to be occurring a lot here this year. Must be a sign from God.

Why are rainbows Multicolored?

Rainbows are multicolored because the white light is refracted spliting it apart into its individual colors

What makes a rainbow?

Rainbows are created by sunlight striking billions of tiny droplets of water in the atmosphere, usually after a rain, but any source of fine water spray can create a rainbow.

Rainbows are caused by the reflection and refraction of sunlight through water droplets in the atmosphere. The water droplets act as individual refractors and reflectors that "split" (refract) the light into the respective colors of the rainbow. The refracted light is reflected off the back surface of the individual rain drops and to the observer.

The physics of the process is the same as the physics behind a prism, i.e. refraction breaks up white light into colors as it passes through a prism. With water droplets, refraction occurs but it is complicated because the droplets are spheres and the light has to reflect from the droplet as well. Nonetheless, the rainbow after a rain is a result based on the principle of a prism.
A rainbow is formed when sunlight passes through a light rainstorm.
The conditions for seeing a rainbow are that the sun be shining in one part of the sky, and that water droplets in a cloud or in falling rain be on the other side. To view a rainbow you need to be at a 42 degree angle. Light is dissipated by the water drops which act as small prisms, the colors refract into the air particles.
When the sun's rays refract light through millions of raindrop's color apears on the horizon, known as a rainbow.
A very good question. Rainbows, simply put, are the end result of white light being factured into several colors. "Now how does this work?" you ask. Well, let's go back and figure out what white light is. According to science, the colors we see are merely reflections of certain wavelengths of light. Every object absorbs light, taking in all of its color. The color that isn't absorbed is what is reflected into our eyes, thus giving the appearance we see. White is a unique color. Contrary to what it looks like, the color white is actually the sum of all colors combined. So, what does this have to do with a rainbow? Have you heard of a prism? Prisms are transparent objects with flat surfaces and refract light. They're often made of glass and can be found in science classes or little fun shops. What happens with a prism is that the white light shining into it is broken up into individual wavelengths of light. The end result: a rainbow. Now, let's go back to the rainbows we see in the sky. They work the same way, only with water. We often times see rainbows at the end of a rain because the rain clouds move away, allowing light to shine down. This light shines through the light mist that is left behind or moving away with the clouds, producing a prism effect. Cool, huh? Did you know that Pink Floyd used a prism on a widely known album cover? ~Apple Juice
Rainbows are caused by the reflection and refraction of sunlight in millions of raindrops.

The Sun must be behind the observer and fairly low for a rainbow to occur. This is why they're seldom seen in the middle of the day. Sometimes, if the light has been reflected twice inside each raindrop, a second fainter rainbow can be seen about 9 degrees outside the first. The colors on the outside one are reversed in order, red being in the inside. A third rainbow is occasionally seen and fourth rainbow is almost on top of the first so it is often not recognized.

A rainbow is actually a spectacular natural optical phenomenon. Individual raindrops act like tiny prisms, splitting the white light from the Sun (or other white light source) into a continuum of different hues, from deep violet to deep red. From any given point BETWEEN the Sun and the rain droplets, a single droplet would appear to refract a tiny speck of light in one particular hue, depending on its position. However, billions of raindrops combine their refractions to form the whole image, a circular arc containing a complete range of colors.

If one were to draw a straight line from the Sun to the Observer, then project that line straight along, it ALWAYS points to the very center of the arc formed by the rainbow. (Since the ground usually interferes with a complete image, one almost always sees just an arc. At higher altitudes, however, the arc continues farther around to form a circle.)

The colors of the primary rainbow are always the same - starting from the outside: red, orange, yellow, green, blue, indigo, violet.

The reason that it is IMPOSSIBLE to "approach" one end of the rainbow is that the rainbow phenomenon simply recedes as the viewer travels toward it. If you use a garden hose to spray fine droplets you can see the entire circle of "rainbow" just a few feet away. A it is a circle there is no "end" to the rainbow.

When the sun is out (and preferably low near the horizon) and it is raining a rainbow occurs as the rays of the sun refract in and reflect from raindrops. Look away from the Sun when it is raining in that direction - away from the Sun - and you can often see 1, 2 or rarely even more rainbows centered around the "anti-solar point" (the shadow of your head).

Why does a rainbow appear bent or arched in a semicircle in the sky?

Rainbows have been the subject of songs and poems, stories and mythology, but there is an explanation as to why rainbows appear as they do. Rainbows are light and you can't touch them. The sun must be shining and must be behind you, and there must be water droplets in the air in front of you. Sunlight shines into the water drops which act as tiny prisms that bend or "refract" the light and separate it into colors. Rays of a rainbow bend twice. As they enter the drops, the rays are bent, then they reflect off the back of the drops and bend again as they exit out the front of the drops. The rainbow is circular because when a raindrop bends light, the light exits the raindrop at a 40-42 degree angle away from the angle it entered the raindrop. The violets and blues bend at a 40 degree angle, and the oranges and reds bend at a 42 degree angle. Light can also enter droplet, be reflected off the back of the droplet, only to be reflected of the front, and then off the back again before leaving. It is bent at each phase in this process, and a second rainbow can appear above the first one. In a double rainbow, the second rainbow will appear where it does because the light will be cumulatively bent some 50 to 53 degrees. This gives it its position "outside" the primary rainbow. Also, the colors will be inverted in this bow. Rainbows don't have "ends" but are full circled, but we can't see this because the horizon of the earth is in the way. If the sun is very low in the sky, either just before sunset or just after sunrise, we can see a half circle. The higher the sun is in the sky, the less we see of the rainbow. The only way to see the full circle of a rainbow in the sky is to be above the ground and have the sun behind you. You would have to look out on the drops from an airplane to see a circular rainbow. Now, this is quite complex, so it's possible you might get away with the old standard, "There is gold at the end of the rainbow and that's what makes the colors." Be sure that you watch your 6-year old closely as he/she might decide to pack his/her bags and go hunting for that bag of gold! Another way you may get away with explaining this off is buying a "prism" (it's a glass drop) and hanging it in a sunny window. It will reflect beautiful spots of light in the room and the effects are quite pleasant to study. Another way to view a full rainbow without leaving the ground is using a garden hose. Have it spray water in bright sunlight with the sun behind you and the spray in front of you. If the entire circle is not visible you can move the hose around to see the rest of the circle. The ones seen from airplanes are more spectacular, though.

Is a rainbow a living thing?

No, a rainbow is not a living thing. In fact, it's not even a thing.

A rainbow is the result of sunlight reflecting from the insides of droplets

of rainwater. It's as real a thing as the picture of yourself that you see in

a mirror, and no two people even see the same rainbow in the same place

at the same time.

How do you explain a rainbow to small children?

Here is a relatively simple definition that can be explained to young children older than five:

Light is made up of many different colors mixed together. When light passes through droplets of water (such as those in the atmosphere after rain) the light gets split up into the different colors of the rainbow.

Take a look at some of the Web Links to the left of this answer for some good explanations for kids.

What does a double rainbow mean?

It means that the light is being refracted in two places. The angle between yourself, water droplets in the atmosphere and the sun is conducive to a double refraction.

A double rainbow is created by light reflecting twice through a raindrop. They are always dimmer and the colors are in reverse order of the more prominent rainbow.

A double rainbow is perceived as a good omen in some ethnic cultures.

Can a rainbow in the sky be seen from space?

No

Rainbows are caused by sunlight glinting off tiny water particles in the sky, bouncing the light back towards the observer. In other words, any time you see a rainbow directly in front of you, the Sun is directly behind you, and your shadow points at the center of the circle the rainbow is describing.

What are the consequences of a judgment?

The Fair Credit Reporting Act states that a judgment may remain on your credit report for 7 years. Many jurisdictions will also use a date a judgment was paid as the expiration date, even though payment does not necessarily constitute a disposition, called a satisfaction of judgment, which is a separate legal action. After a judgment is granted, the plaintiff may garnish the defendants wages, file an extention of the original judgment to extend the time period it may legally show on a consumer's credit report, or place a lien upon any property owned by the defendant. The latter might prevent sale or refinance of that property.

What is the Rainbow Bridge?

Just this side of heaven is a place called Rainbow Bridge.

When an animal dies that has been especially close to someone here, that pet goes to Rainbow Bridge.

There are meadows and hills for all of our special friends so they can run and play together.

There is plenty of food, water and sunshine, and our friends are warm and comfortable.

All the animals who had been ill and old are restored to health and vigor; those who were hurt or maimed are made whole and strong again, just as we remember them in our dreams of days and times gone by.

The animals are happy and content, except for one small thing; they each miss someone very special to them, who had to be left behind.

They all run and play together, but the day comes when one suddenly stops and looks into the distance. His bright eyes are intent; His eager body quivers. Suddenly he begins to run from the group, flying over the green grass, his legs carrying him faster and faster.

You have been spotted, and when you and your special friend finally meet, you cling together in joyous reunion, never to be parted again. The happy kisses rain upon your face; your hands again caress the beloved head, and you look once more into the trusting eyes of your pet, so long gone from your life but never absent from your heart.

Then you cross Rainbow Bridge together....

What is a rainbow?

A rainbow is created when invisible light filters through a clear substance or material like rain. The Light we can see like the sun, is not actual light, what we see is fire, what happens is Light itself becomes inviable when Dark Burns. The Sun is made of light and Dark, When Fire burns like the sun does light is released from dark. This means space itself burns around the sun and light comes from the suns centre. A true rainbow is created when invisible light gets caught in a Form of Clear sphere type lens, just like a Raindrop. The Invisible light filters outwards, If the Liquid was shaped like a Magifying glass then the Invisible light would Compress into a Beam of Light. But an actual rainbow is created by a Sphere type clear Liquid like a raindrop. A Triangular Clear Object acts like a Mirror when invisible light hits it, so the best or the Rainbow Shoot out mostly at an angle. If you use a Sphere of Glass what is Mostly Hollow and You had i Liquid to slow down the Invisible light, The Invisible light would Reflect into the Centre of the Sphere, The Outside of the Sphere would create a Sphere Shaped Rainbow. This Is Only my Theory, as I dont has the means to experiment, and it is something ive found out in my own imagination. I never copied this idea from anything.

It is a rule that violet light bend that most and red color bend least way. Most of the light passes through the rain drop. Because of bending of colors in different ways and on different angle each color that emerges from raindrop produce a spectrum of colors. As only single color from each drop reaches to observer, so there are number of raindrops from which each rain drop reflect the light back to an observer at slightly different angle, as to produce different primary colors of rainbow. Secondary rainbow appears above the primary rainbow. When two colors reflection occur inside a raindrop at such angle that it results into secondary rainbow. When weaker light that start emerging to produce a dimmer rainbow effect. Refraction happens as light enters and leaves a prism. Red light is refracted the least and violet light is refracted the most. This causes the different colours in the light to spread out to form a spectrum. Separating the colours like this is called dispersion. We say that the light has been dispersed.

Does the rainbow touch the ground?

A rainbow is a trick of the light and has no physical properties. The water drops that cause the light to show up as a rainbow can come down and touch the ground, so a rainbow can look like it is touching the ground around waterfalls and similar water features, and is so high up in the air that it appears to touch the horizon. But the rainbow will move as the observer's eyes move, so you can never get to the rainbow, but it may appear to someone else that you have reached the end of the rainbow.
If you were in a plane looking down on a rainbow you would see a complete circle. From below we only see part of it because of the Earth's curve etc. And as described above only you can see the particular rainbow that you are seeing. It looks different to anyone else because of the way the millions of raindrops reflect light individually and so differ even to someone next to you.
