wy is the ski blu?

Answer 1

Good question! I think we all wonder about this at some point in our life.
It has to do with the chemical make up of the atmosphere, reflection and so on. Here is a link that will describe this in detail.

Answer 2

If you mean 'why is the sky blue?'

It's because the atmosphere is a colloid. A system of small solid particles suspended in a set of gases.

The diffraction of sunlight by these particles is called the Tyndall Effect and is what causes the blue colour.

When the angle of the sun's ray changes later in the evening the diffraction pattern of the light off the particles causes the colour of the sunsets (orange/red)

Answer 3

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

Answer 4

Blue/Violet light has the greatest frequency and thus more energy. It can travel through the atmosphere without being deflected as much as the other light waves and so it is the only color that reaches our eyes to make the sky appear blue.

Answer 5

Because light gets diffused by the atmosphere, like a prism, and broken down into its constituent spectra, the most visible of which is blue.

And isn't it just beautiful!!

Answer 6

the sky is blue because of the refraction of light from the water molecules on the atmosphere like a prisim but only for blue

Answer 7

The what, huh?
Are you sayin 'wy' is a type of 'ski'?
But why would that be a question?

Answer 8

it is the principle of dispersion of light....
the atmosphere acts like a prism and disperses white light into its components.... blue is dispersed the least .. so the sky appears blue

Answer 9

My skis are red and white.

Answer 10

I don't like ski's much, prefer snowboards which is red.
