Answer 2

The blue color of the sky is due to sunlight scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Very little of the red, orange and yellow light is affected by the air. However, much of the shorter wavelength light is absorbed by 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 lighter 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 lighter or white. Thats basically it. Hope I helped.

The air around the Earth contains tiny bits of dust. These are too small to see, but they’re big enough to scatter light. Blue light is scattered more by dust than red light. As the light from the sun comes through the atmosphere, the blue light is scattered. The scattered blue light bounces from dust particle to dust particle, spreading blue light through the whole sky. This is why the sky normally appears blue.

When the sun is low on the horizon, the light has more air to pass through as it travels through the atmosphere. Also the lower part of the atmosphere close to the horizon contains much more dust, so the blue light is scattered and the red light reaches your eyes. This is why sunsets are red. The dustier and smokier the atmosphere, the red the sunset.

Answer 4

White light is made up of many colours. As the white light passes through the atmosphere, the light is scattered and the colour that happens to be most scattered is the blue light. This means that the blue colour is separated from the other colours in the white light and hence, that is why the sky is blue.

Answer 5

According to the website: http://www.why-is-the-sky-blue.tv/why-is-the-sky-blue.htm

"Transmitted light (from the sun, light bulbs, fire, etc) is made up of a spectrum of colors. The longest wavelengths of light are on the red end of the spectrum and the shortest wavelengths are on the blue/violet end of the spectrum.

When transmitted light such as sunlight enters our atmosphere it collides with the oxygen and nitrogen atoms. The color with the shorter wavelength is scattered more by this collision. Because violet and blue are the shortest wavelengths the sky appears to be violet / blue. But because our eyes are more sensitive to blue light than they are violet light, we perceive the sky as blue.

Our eyes contain thousand of rods and cones, which are the receptors for light. Whenever one of the 3 Stooges pokes you in the eye you see a giant blue spot. This is because the blue receptors have been activated. Blue is one of the primary colors and thus more easily activated and seen by our eyes."

Answer 6

Anyone who tells you it's reflecting the sea is dumb, it's the other way round, the sea reflects the colour of the sky, the real answer is that the light is diffracted by the particles in the air and the spectrum that comes out is blue.

Answer 7

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.

Answer 8

It is only blue on a clear day and the light of the sun's rays lightens the inky blue black night sky!

Answer 9

Because the shortest light wavelengths are blue, and these are the ones we see being emitted from the sun. ( we can't see the long light wavelengths)

Answer 10

the reflection of the sea surface causes it to look blue and..
the ozone gas of course it makes the sky look blue

pls choose me if u think mine is the best answer
thank you

Answer 11

it reflects blue light and absorbs the other colours in the spectrum, thats why anythings the colour it is.
