Answer: The sky is the layer of atmosphere under which we live, It is made up of several colorless gases. The gasses interact with the light coming from the sun to give the impression of colour.
A bit of background: The white light from the sun is a mixture of all colours of the spectrum. Each colour of light ahas a wavelengths. The visible part of the spectrum ranges from red light (wavelength =720 nm), to violet (wavelength =380 nm), with orange, yellow, green, blue and indigo between. The human eye reacts most strongly to strongly to red, green and blue wavelengths. This gives us colour vision. The explanation: Light passing through a clear fluid with suspended particles is scattered. Some wavelengths like blue are scattered more strongly. The first person to notice this and experiment with it was John Tyndall in 1859. So he got to mane the effect the Tyndall Effect. He made three important observations: * From the side, (the way we see most of the sunlight in the sky) the beam can be seen by the blue light it scatters * The light seen directly at the end (looking towards the source) is red. This is the way we see the sunlight at sunset
* The scattered light is polarized. This is why polarized sun glasses make some parts of the sky seem darker.
Some early researchers (Tyndall and Rayleigh) thought that the blue colour of the sky must be due to small particles of dust and droplets of water vapour in the sky. Later scientist discounted this and proposed that oxygen and nitrogen molecules are the cause of the scattering.
In 1911 Einstein did the math to prove that the molecules could cause the scattering. Technically the molecules scatter light because the electromagnetic field of the light waves induces electric dipole moments in the O2 and N2 molecules,
Blue sky means that the sky is blue .Sky is the appearance of the upper atmosphere. Blue is the color of the sky which is the color of the sign in box.
Yes i have. I have a shirt that is sky blue pink. Have youseen the color sky blue pink?
The sky is the color blue. The blue sky has white clouds.
Gases in the sky are not blue, the blue of the sky is caused by light scattering. However, oxygen is blue if you liquefy it.
because the sky is blue
sky and blue
my sky blue lady
this song is technically about a blue sky
wit is when the sky is not blue

The sky is blue and it reflects off the ocean so it is blue too. That's why when the sky is grey they ocean is grayish.
Yes, scattering does cause the sky to get blue. Yes, Rayleigh Scattering makes the sky blue.

the blue sky does not glow unless you are on drugs
Blue Sky is a Movie starring Tom cruise
dark blue the sky is light blue
No, the sky is not blue because the sea is blue. The sea water is actually clear, not blue, so we can automatically rule out that the sky is blue because the sea is blue. However, if you see the sea as blue, then it's more correct to say the sea is blue because the sky is blue.

No i think the sky is blue because the reflection of the ocean or could it be the sky is blue and it reflects on to the ocean?
The sky isn't blue, its a just a reflection from the sunlight onto the water, thus creating the illusion that the sky is blue...
The sky blue dsi is for both boys and girls. I know boys and girls who have the sky blue dsi.
no that doesn't make sense when they say sky blue it means it is a blue colour that looks like the sky
that's easy no it is not yes it is fine its not o sorry um o yes a blue sky car definition is that the color is not blue sky but sky blue which is basicly light blue
No, the sky isn't blue because of air pollution it is blue because of the water particles reflecting of the sunlight which makes the sky blue
i think you should decide for yourself (my favorite is sky blue!)
