why is the sky blue and why is the sun yellow?

Question

I know the answer just waiting for someone who has the same answer

Answer 1

The right answer as no one has gotten it right yet:

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.

Any Why is the Sun Yellow:

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

Best way to think about it is like a coloured piece of glass. If you hold up a blue piece of glass to a white light, as the white light (with the entire spectrum of colours) passes through, the blue glass, certain colours are absorbed, with the exception of blue. So once the light has passed through it will appear blue.
Same with the sky, the blue light is actually what appears to us after the light of the sun passes through the atmosphere and NOT because of the colour of the sea as many people think!!!
The intensity of the light from the sun passing through the atmosphere makes it appear yellow.
By that same token, the red sun of a sunset appears yellow because it is low on the horizon and the light has to pass through more atmosphere and the light waves appear red and orange.
There is a technical answer involving the wavelength of different coloured light and the refractive index of the atmosphere, but my version is easiest to understnad.

Answer 3

the sky is blue because the sun is yellow.

J/K! the sky is blue because of the reflection of the ocean or at least that's what I was taught by a teacher a while a go, as far as the sun i really have no clue.
