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.

Can rainbows appear at night?

Yes, but they're noticed much less often, and are called "moonbows". They're

naturally much dimmer than the daytime variety, with colors much less brilliant.

The set-up is the same, with the moon being the source of light. The moon is directly

behind you, in a clear patch of sky, and the air directly in front of you has a lot of

water droplets in it, either from a recent rain, or even a very heavy fog.

The radius of the circular moonbow is 42 degrees, and its center is directly opposite

the moon, exactly as in the daytime rainbow.

What is the cost for a new Rainbow vacuum?

The regular price for a brand new Rainbow vacuum is usually around $2,000 to $2,500. They can be purchased online for cheaper, around $1,000 to $1,500 on sites like Amazon.

Can rainbows make a full circle?

Not if you're on relatively flat ground. The rainbow you see can be a complete circle

if you're on a high place looking down into a valley, or if you're looking down out of

an airplane.

How many clours are there in the rainbow?

All of them are ... every color that anyone has ever seen, or that can be seen.

There's no limit to the number.

What is Rainbow Dash's FULL name?

Her full name appears to be Rainbow Dash.

Are there only 7 color of the rainbow?

Every color that the human eye can detect, every shade of paint that was ever

mixed, every nuance of tone ever suggested by light, every hue of fabric that was

ever dyed, all the thousands of named colors and thousands more that were never

yet named, are all in the rainbow. The number of them that you can pick out is

limited only by the ability of your retina to distinguish between colors with nearly

equal wavelengths.

Are colors of rainbow ever in different order?

No. However, I saw some of them mixed in a little

How can rainbows be seen only when the sun is behind the observer?

Light rays from the sun enter suspended raindrops in the sky after a shower. The
light enters the droplets and total internal reflection occurs, and the rays are
reflected outward, close to the direction back to the sun again. In the reflected
light, the colors are slightly spread out.
So, if the sun is in front of you, or to the side of you, then the light rays that are
reflected and come out of the raindrop are not headed in your direction, and you
can't see them.

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.

Can you see a rainbow in the day sky?

The rainbow is almost always in the day sky, produced by sunlight.

Very rarely, one can appear in the night sky, produced by moonlight.

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.

Can you see a rainbow at any time of the day?

No, you can only see them in daytime, while the sun is out in a clear sky.

Rainbows are caused by an optical andmeteorological phenomenonwhich is caused by sunlight reflecting off water droplets ontheEarth's surface at a 42 degree angle.

This causes a spectrum of light,resultingin a multi-coloured arc that we call a rainbow.


Rainbows are most likely to occur around lakes, rivers and waterfalls, where there is plenty of mist and dew. They also appear after a rainy shower when the ground is wet and the skies are clear for the sun to shine throughuninterrupted.

Can a laser pointer make a rainbow with a prism?

A laser beam consists of a single frequency of light, therefore it cannot form a spectrum or rainbow.

Why rainbow bent?

Because AT the location of every water droplet in the air, the angle

between the direction to the sun and the direction to your eye must

be the same. The only shape in which that's possible at every point

is a circle.

What acts as as the prism to produce a rainbow in the sky?

from my experence i think it is water because it only happens after rain and during sunny days and you put your house to mist you can see the rainbow

What color of light are the colors of the rainbow combined?

Mixing the light colours of the rainbow will produce white light (i.e. daylight).

Does rainbow clothing store pay weekly or biweekly?

Rainbow Clothing Store typically pays its employees on a biweekly basis. However, payment schedules can vary by location and position, so it's best to check with the specific store or refer to the employee handbook for accurate information.

Are leprechauns attracted to rainbows and dark colors?

If you say they are, then they are. Leprechauns are made-up, so you're free
to give them any characteristics you'd like them to have.

Seems to me I've heard that leprechauns live at the end of rainbows. If so, then
that would suggest that there's something about the end of a rainbow that attracts
them. (Maybe it's the fact that, like them, the end of a rainbow doesn't exist.
Ya reckon ?)

What is a double rainbow meaning?

Why do rainbows come out when it rain?

About how long are you able to see a rainbow in the sky?

As long as the sun is behind you in a clear patch of sky

and the air in front of you is loaded with water droplets.

Why does a rainbow show colors from reds to violet?

There's a broad band of wavelengths of light coming from a rainbow. They range

from wavelengths that are too short for your eyes to detect, all the way to

wavelengths that are too long for your eyes to detect. Within that band of

wavelengths is the total band that your eyes can detect, and you see them

as a spread out display of all the colors that your eyes and brain can work

together to perceive.

How does a rainbow work using dispersion?

Rainbows form when sunlight is dispersed and refracted by water droplets in the atmosphere. The different colors of the rainbow are a result of the different wavelengths of light being separated as they pass through the water droplets. This dispersion causes the visible spectrum of colors to be displayed in the sky.
