why is the sky blue?

Answer 1

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 2

Sunlight passes through earth's atmosphere before it reaches your eyes. As it passes through the gas molecules break up or scatter the sunlight in to many parts. You know that a rainbow is yellow orange green blue and indigo and violet, right? The gas molecules in the atmosphere reflect off the blue better than the red or violet, so the sky appears blue because of the blue wavelights.

Answer 3

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

Refraction of light

i hope this is a rhetorical question.
Why is the sea green and blue.
