wHY IS THE SKIY BLUE?

Question

rEALLY FOR THE KIDS AND ME OF COURSE WHY IS THE SKY bLUE????

Answer 1

LIGHT IN THE AIR
Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule. Then what happens to the light depends on its wave length and the size of the thing it hits.

Dust particles and water droplets are much larger than the wavelength of visible light. When light hits these large particles, it gets reflected, or bounced off, in different directions. The different colors of light are all reflected by the particle in the same way. The reflected light appears white because it still contains all of the same colors.

Gas molecules are smaller than the wavelength of visible light. If light bumps into them, it acts differently. When light hits a gas molecule, some of it may get absorbed. After awhile, the molecule radiates (releases, or gives off) the light in a different direction. The color that is radiated is the same color that was absorbed. The different colors of light are affected differently. All of the colors can be absorbed. But the higher frequencies (blues) are absorbed more often than the lower frequencies (reds). This process is called Rayleigh scattering. (It is named after Lord John Rayleigh, an English physicist, who first described it in the 1870's.)



WHY IS THE SKY BLUE?
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.







As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.









THE BLACK SKY AND WHITE SUN
On Earth, the sun appears yellow. If you were out in space, or on the moon, the sun would look white. In space, there is no atmosphere to scatter the sun's light. On Earth, some of the shorter wavelength light (the blues and violets) are removed from the direct rays of the sun by scattering. The remaining colors together appear yellow.

Also, out in space, the sky looks dark and black, instead of blue. This is because there is no atmosphere. There is no scattered light to reach your eyes.

Answer 2

i believe light travelling from the sun passes through earths atmosphere and is refracted slightly due to water vapour and this refraction is seen in a blue colour (prism effect). At night the blue sky is clear and we see through the atmosphere into space with a beautiful view of the stars. Apparently, If the earths atmosphere was thicker or thinner the sky would appear to be more reddish or colourless respectively.

Answer 3

It is a matter of refraction. When the sun is overhead, light is passing through the air and is scattered across the sky. Different light waves refract differently, leaving a more-or-less blue tint. In the evening, when light is passing through more of the atmosphere, the refraction leads to reddishing light in the sky.

Answer 4

Elizabeth and Besty S answered this question thoroughly and correctly. They said what I would have stated. The sky is blue because due to the Rayleigh scale the wavelength associated within the blue range is reflected and picked up by our eyes.

Answer 5

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

Answer 6

light is made of seven colors, though normally our eyes do not see individual colors.
when sunlight hits the atmosphere of the earth, however, blue breaks off from the ohter colors and is scattered in the air.
seperated like this it becomes visible, and that is why the sky is color blue.

Answer 7

Baically the sky is blue because the sunlight coming to us is scattered by the earth's atmosphere.

Answer 8

this is beacause the dust particles in the sky reflect this the color the most and so all the other colors get overshadowed .
did you know that the same dust particles when wet (by rain) reflect many more colors to give you the rainbow efect?
it is the same concept here.

Answer 9

I can't remember the exact reason, but it has to do with the way light refracts in different frequencies. Each color is in a different frequency. That's why the sunset is orange. The sun reflects differently when it is at a different angle. You could probably research this one.

Answer 10

i have 2 answers for this one

#1 God helped make it that way

#2 because the sunlight from the sun reflects into the ocean on to
the sky

ok heres 1 for u y is the grass green????
