Why is the sky blue???

Answer 1

First and foremost there is nothing really as sky. We call the blue colour we see above our head as sky . It is the dispersal of the light of the sun in the atmospher of the earth that looks like a a vault being in place over theearth. there is nothing actually; but the air blanket upto a certain level and beyiond tht nothing and itwould look dark as even light would have nothing to reflect upon. Even light you see only if it reflects and falls on something . We will not be able to see light if it travels through vacuum.it is visible only when it travelks through a medium. Light that enables us to see erything is itself invisible if it does not have a medium to pass through and reflect upon.And if you look into a very bright light directly , you will be blinded and you will see nothtring .
the sky is blue because the sun's light is dispersed through the earth's atmospher and all the clours except the blue spectrum is absorbed by the atmospher and the blue alone id reflected .

Answer 2

The colour of the sky is a result of diffuse sky radiation and the fact that air is actually a very transparent blue color. On a sunny day the Earth sky usually looks as a blue gradient — dark in the zenith, light near the horizon (due to Rayleigh scattering). It turns orange and red during sunrise and sunset, and becomes black at night.

Answer 3

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.

Answer 4

It's due to a phenomenon called Rayleigh scattering. When light encounters particles much smaller than the wavelength of light, the light scatters. Atmospheric gas is an enormous resevoir of such particles. Short wavelengths scatter the most effectively, and blue has a short wavelength, so the blue light scatters and appears to fill the sky. Note that violet has a shorter wavelength than blue, but the human eye is not very good at seeing violet, so blue appears to dominate instead.

Answer 5

The sky is blue because water in the air is refelected by the sun and makes the sky look blue.

Answer 6

its blue due to the oxygen in our atmosphere. As the lightwaves from the sun are absorbed it gives of a bluish tinge

Answer 7

god made it that way for a reason, we just dont know why yet.
