Why is the sky blue?

Answer 1

because

Answer 2

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.

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.

Answer 4

The sky is blue, because sunlight is diffused in the atmosphere. Blue light has has a shorter optical path length (around 49 km/30.6 miles) than red light (around 180 km/112.5 miles). Therefore, the diffusion process of blue light is more efficient. On the other hand, sunrise and sunset are red because light has to cover a longer distance through high-density areas within the atmosphere. Blue light is substantially diffused, so the sky turns red.

Answer 5

Hydrogen and oxygen mix to create water vapor, and that vapor is reflected through the light, and it happens to be on the blue side of the sprectum this light, because we all know water is clear, despite what the ocean and the sky tells us. (clouds are made of the same stuff the sky is made out of), and well...

Answer 6

The way it was explained 2 me.
The sky is not in fact blue, it's colourless.
It contains millions of specks of dust, pollution & water.
It's blue from the reflection of the Oceans, that cover most of this planet.

Answer 7

The real answer it because the dirt particles in the sky reflect the prismatic color of blue.

Answer 8

the sky is blue because it would look like hell if it were red

Answer 9

Molecules in the air scatter blue light from the sun more than they scatter red light. From: see link

Answer 10

It's just the way the light particles are scattered before they get to your eyes. Blue is the color of light that we see when it's all said and done.

Answer 11

Diffuse sky radiation.
