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.
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.
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
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.
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 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?
It is when there are two rainbows on a place rather than so above one rainbow is another therefore double rainbow
Why do rainbows come out when it rain?
Because in order to make a rainbow, there has to be water in the air.
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.
Beauty is in the eye of the observer. If something
is pretty, that's because you think it is.
Is the rainbow a diffraction of light?
No - it's a combination of refraction and reflection. The sun's light enters a spherical water drop at a grazing angle, and refracts inwards. Some of the light then reflects off the rear surface of the drop, and exits the drop (refracting again on the way out). In the process the light is spread into its constituent colours and reflected through 218 degrees.
==========================
Answer #11/2 :
Answer #1 is OK, except that where it reaches the part about
"... spread into its constituent colours...", that's dispersion.
What must happen to cause a rainbow?
In order for a rainbow to happen it needs to rain. Just after you see the rain is gone a rainbow appears for a short moment. A mixture of rain and light creates a rainbow. You could even use a glass with water and sunlight for a rainbow to appear.
