why is the sky blue?

Answer 1

This question has been asked SO many times!
Look in the archives to find the answer;

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.

Answer 3

he color of the sky is a result of diffuse sky radiation and the fact that air is actually a very transparent purple 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.

Sky luminance distribution models have been recommended by CIE (the International Lighting Commission) for the design of daylighting schemes. Recent developments relate to “all sky models” for modelling sky luminance under weather conditions ranging from clear sky to overcast sky.

Answer 4

The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere. This scattering, called Rayleigh scattering, is more effective at short wavelengths (the blue end of the visible spectrum). Therefore the light scattered down to the earth at a large angle with respect to the direction of the sun's light is predominantly in the blue end of the spectrum.

Answer 5

the sky is blue due to scattering of the light waves by the gas molecules in the atmosphere, called Rayleigh scattering. the longer wavelengths, like red, are less affected than the shorter wavelengths, like blue. the blue light is scattered in every direction by the gasses in the atmosphere, making the sky blue wherever you look during the daytime.

Answer 6

Being that everyone's already explained the refraction bit, it might be worth noting that oxygen is ever so slightly blue, or is that ozone? Either way, they're both oxygen

Answer 7

cause god wanted to be that way just like its black at night u know from the sun moon hiding the sun ight bathroom break

Answer 8

light refraction. just like its red in the evening.

Answer 9

reflection of the ocean

Answer 10

Because God chose not to have it green!
