Why is the sky blue?

Question

And if your going to answer because it relflects the ocian.... why is the ocian blue.. sky, ocian.....?

Answer 1

the ocean is blue because of the color of the water and the composition of hydrogen and oxygen... well technically the sky is blue because the color blue is scattered in the atmosphere and not on the land(color from the sun ... the rainbow colors) so that's why we see the sky as blue

Answer 2

The sky is blue due to an atmospheric effect called Rayleigh scattering - certainly not because its reflecting the ocean which people sometimes say! Rayleigh scattering involves the scattering of light by molecules smaller than the wavelength of light. It has a smaller effect on colours with longer wavelengths and that is why the sky is blue - and also in fact why the sun is yellow - if you added up all the blue tint in the sky and focused it in the area of sun you would get its actual colour of bright white, which is what you’d see in space.

Physicists used to say that Rayleigh diffraction was responsible for the reddish tint in sunrise and sunset because the light had to travel through more atmosphere to reach us however this is currently disputed and there is another optical theorem at work called 'Lorenz-Mie theory'.

Kind regards.

Answer 3

The sky is blue because of Rayleigh scattering. Dust particles in the air are about the size of a wavelength of blue light. This wavelength gets scattered more than others. It's the same reason a sunset is red. As the sun moves closer to the earth's horizon, the particles are larger. Red is a longer wavelength than blue and this light gets scattered more.

Answer 4

Essentially because the shorter wave length light (blue) bounces around off of the gas molecules. The longer wavelengths (red, orange, etc) pass right through. This is known as Rayleigh scattering. See the link for a detailed source.

Answer 5

because in the sky there's gas and dust..and when the sun makes it bright...the ocean yea its reflecting the sky like a mirror

Answer 6

Congratulations! You are person number 1474 to ask this very same question.

Answer 7

Refraction of sunlight through the water vapor in the atmosphere and the reflection of oceans.

Answer 8

Just like we ask ourselves, why is the grass green!
