Why is the sky blue?

Report as

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.

It is due to colors in sunlight, the angle at which solar illumination travels through the atmosphere, the size of airborne particles and atmospheric molecules, and the way our eyes perceive color.

Technically its not. Its just the way light reflects off your pupils

Because it reflects the color of the ocean. It's like a mirror.
Have you noticed flashing a light on a mirror?
It reflects the light. That's how it works.
It reflects the light including the color of the ocean during daytime.
Ocean surface is like a mirror.

Our teacher in Science explained this to us in 3rd grade.

So I've made a practical experiment on this ^_^

Eurica!

Backwards. Wavelengths of light pass through matter differently depending on the material?s composition. Blue wavelengths are transmitted to greater depths of the ocean, while red wavelengths are absorbed quickly. Water molecules scatter blue wavelengths by absorbing the light waves, and then rapidly reemitting the light waves in different directions. That is why there are mostly blue wavelengths that are reflected back to our eyes. Oceans reflect back the blue of the skies only at low angles and when the ocean is relatively flat. The sky does NOT reflect back the blue of oceans.

because blue is the only colour not absorbed in the atmosphere
