why is the sky blue?

Answer 1

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 2

Transmitted light (from the sun, light bulbs, fire, etc) is made up of a spectrum of colors. The longest wavelengths of light are on the red end of the spectrum and the shortest wavelengths are on the blue/violet end of the spectrum.

When transmitted light such as sunlight enters our atmosphere it collides with the oxygen and nitrogen atoms. The color with the shorter wavelength is scattered more by this collision. Because violet and blue are the shortest wavelengths the sky appears to be violet / blue. But because our eyes are more sensitive to blue light than they are violet light, we perceive the sky as blue.

Our eyes contain thousand of rods and cones, which are the receptors for light. Whenever one of the 3 Stooges pokes you in the eye you see a giant blue spot. This is because the blue receptors have been activated. Blue is one of the primary colors and thus more easily activated and seen by our eyes.

Blue is also how I feel when my baby leaves and my hound dog dies. Also, how I feel when the cops pull me over and I see their blue lights flashing in my rear view mirror. Then, again, blue is the color of the K-mart special, so this color isn't all bad.

So, why is the sky blue? It is because blue light from the sun strikes the air molecules and scatters and our eyes perceive it as blue.
Why is the sky blue, you ask? Blue in sunlight collides with air molecules and our eyes see it as blue.
Sunlight collides with air, scatters blue wavelengths.

Answer 4

bcause short wavlength light (blue light) is scattered more easily by the microscopic particles in the atmosphere. It's the same reason the sunset looks red because the blue light has been taken out

Answer 5

Because God loved blue

Answer 6

First of all thats how God made it out to be. But you also have to suggest that the ocean has to do with some of it since most of the Earth is water...

Answer 7

i actually typed this question into yahoo search engine (cos one of my small sons asked this question)..try it your self, it gives you a very in depth answer on science and chemical rays that reflect and show the light to be blue,...very deep and interesting.

Answer 8

because that what colour the ozone reflex and absorbs the others and at night it becomes red and orange because it runs out of blue molocules

Answer 9

because of the sun's light and it's reflection on earth. thats also why the oceans look blue also.

Answer 10

Raliegh scattering
