The Sky is Blue

[lavender]

Try to argue with that, suckers!

 

[LilMissT]

Grass is er, brownish and covered with white fluffy stuff

 

[tulip2lipservice]

hmmm and the grass is green

I am sure if somebody really wanted to in here you know they would try.

Peace,
Tulip

* I seem to enjoy that mantra however, the sky is blue and the grass is green.

 

[Tap-Out]

what about durring a storm? or how about in the evening when the sun goes down? Where's your precous blue then? Answer that one

 

[tulip2lipservice]

dang Mis beat me to it and

you know what she is right.

Peace,
Tulip

Finals time, lavy?

OK, you're on. The sky is NOT blue. Objects are colourless. It is merely a trick of the refraction of light, and the human apparatus of perception, that the sky appears to be blue to us.

There.

 

[Freya]

Well, it's really more of a bluish grey shade to be specific. With lumpy white things floating around.

 

[modest mouse]

Try to argue with that, suckers!

Actually the sky is a collection of wavelenths, some visible some not, that looks blue to teh eye. Its actually a multitude of colors.

 

[SimplySouthern]

Yep, the sky is black at night.

And what if the sky isn't really blue but we only perceive it that way?

Perception is a tricky thing, my friends.

Sidenote: Hi lavy-licious!

 

[Rambling Rose]

*laughing*

You asked for it, Toyota!

 

[mig]

The sky is definitely blue.

Big G said so,and so did little J.

There.

And it's all W's fault that we can't see it for how it truly is.

Sorry, RED, just wanted to help.

Actually that depends which sky you're talking about... for example, the sky is NOT blue on Mars.

Here are some other examples of when the sky is NOT blue:

• At Night
• On the Moon
• When the air heavily laden with pollutants
• When the air is very humid (and contains a few other things)
• Near sunrise or sunset
• When it is cloudy...but this doesn't count because strictly speaking clouds obscure the sky

Technically speaking even when the sky "is blue" it is actually not blue at all--what we see is simply the air glowing blue. This is caused by reflected sunlight, and it is blue because tiny air molecules reflect blue light more efficiently than the other colors. If the reflecting molecules were larger, however, such as the large water drops in a cloud, then all colors would be scattered. That is why clouds appear white.

Strangely enough, the blue hue of the sky depends on the reflectivity of the underlying surface. Thus, the sky looks bluer over the oceans than it does over a reflecting ice or snow-covered surface. This tact was used by early polar explorers to detect open water. Haze or pollution causes the sky to look washed out. The bluest skies are seen in pure mountain air at locations far from urban pollution.

Sadly enough, as industrial haze continues to build up, it is rarer all the time to see a really blue sky in many parts of the world. Perhaps the bluest sky in the world can be seen from the summit of Mauna Loa, Hawaii (14,000 feet). From this location on a clear day, the sky looks almost violet, the surrounding oceans, the altitude and the clear air all contributing to the hue.

Dillenger did I ever tell you

that you have an abundance of information in that brain of yours. Couldn't you just agree or disagree? LOL

Perception is reality, right? Isn't that what you think, or do I have you wrong?

 

[Dillinger]

I have been known, at times, to percieve that perception is indeed reality. Though there are many levels of perception and much complication depending on whether we're talking individual perception or group perception.

 

[theGatsby]

Percetion is reality? Singular perception versus group perception? Does a similar perception held by many people mean that perception is correct? Remember most of the the world's population once precieved the planet to be flat.

Men go crazy in congregations, but can only be healed one by one.

 

[bluntforcemama]

The winter dusk is orange. Perception is reality to that individual who perceives. Why do you think half of the human race is fucked up?

Then... to them... in their shared reality, it was...

 

[REDWAVE]

Singular or group?

Good question. Afraid I don't have any really good answers. But that doesn't bother me too much, because I know no one else does either! Even the greatest philosophers have wrestled with questions like that.

I suppose since each person is a separate organism, individual perception is primary. However, many people's conceptions and even perceptions are shaped by societal conditioning, so there is somewhat of a circular effect.

See what a can of worms you opened here, lavender?

Indeed it was. Reality is what you make of it after all. To the crying child in the middle of the night the boogie monster in the closet is as real as that loving kiss from Mom or Dad that makes it go away.

The sky is colorless......

Light is made up of electromagnetic waves.

The distance between 2 crests in this wave is called the wavelength.

White light (ie. Sunlight) contains all the colors of the rainbow.

The amount of light scattered for any given colour depends on the wavelength of that colour.

All the colors in white light have different wavelengths.

Red light has the longest wavelength.

The wavelength of blue light is about half that of red light.

This difference in wavelength causes blue light to be scattered nearly ten times more than red light.

This scattered blue light is what makes the sky blue.

All other colors (with longer wavelengths than blue light) are scattered too.

Blue light's short wavelength causes it to be scattered the most.

(The shorther the wavelength of the color, the more that color gets scattered by the atmosphere)

Actually, violet has the shortest wavelength of all colors. Violet is scattered even more than blue light. However, our eyes are much more sensitive to see blue than violet, therefore we see the sky as blue.

Try to argue with that, suckers!

So Lavy, how'd we do?

 

[The Heretic]

Try to argue with that, suckers!

You have obviously never been to the Pacific NorthWet. Here the sky is grey and you have to use a mirror to verify that because if you look up into the sky you will drown.
