y is the sky blue?

Answer 1

The sky appears blue on days when there is little pollution such as dust in the air. When the air is clear sunlight is scattered by air molecules in all directions. The shorter the wavelength of light the greater the scattering or S is inversely proportional to the fourth power of the wavelength. Since blue is the shortest of the visible wavelengths it will be scattered the greatest. This form of scattering is called Rayleigh scattering. When dust or particles are in the air another form of scattering called Mie pronounce Me, is present. This scattering scatters all wavelengths and primarily in the direction of your line of sight so that now the sky appears to be more white. I hope this helps a little. This was an excellent question.

Answer 2

Deb: I'm sure that you'll find that the opposite of what you're saying is true - that the colour of the sea is the direct reflection of the colour of the sky. Hence, when the sky is bright blue, the sea looks deep blue, and when the sky is grey the sea would look grey.

If you really believe that the sky takes on the colour of the sea, have you ever wondered why the sky isn't green over the amazon jungle?

Answer 3

the sun reflects off the ocean and makes the sky blue



On a clear sunny day, the sky above us looks bright blue. In the evening, the sunset puts on a brilliant show of reds, pinks and oranges. Why is the sky blue? What makes the sunset red?

To answer these questions, we must learn about light, and the Earth's atmosphere.



THE ATMOSPHERE
The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%). Argon gas and water (in the form of vapor, droplets and ice crystals) are the next most common things. There are also small amounts of other gases, plus many small solid particles, like dust, soot and ashes, pollen, and salt from the oceans.

The composition of the atmosphere varies, depending on your location, the weather, and many other things. There may be more water in the air after a rainstorm, or near the ocean. Volcanoes can put large amounts of dust particles high into the atmosphere. Pollution can add different gases or dust and soot.

The atmosphere is densest (thickest) at the bottom, near the Earth. It gradually thins out as you go higher and higher up. There is no sharp break between the atmosphere and space.



LIGHT WAVES
Light is a kind of energy that radiates, or travels, in waves. Many different kinds of energy travel in waves. For example, sound is a wave of vibrating air. Light is a wave of vibrating electric and magnetic fields. It is one small part of a larger range of vibrating electromagnetic fields. This range is called the electromagnetic spectrum.

Electromagnetic waves travel through space at 299,792 km/sec (186,282 miles/sec). This is called the speed of light.

Answer 4

The color of the sky is usually a direct reflection of the ocean. I have been on the Mendocino Coast when the sky was a crazy blue, then looked to see the ocean was also as blue as could be. Then I've been there when the sky was a little gray, looking at the water I found the same there.

Answer 5

It is not ozone, it is not the colour of oxygen, it is not the reflection of seawater, it is, as has been pointed out and described by people who know what they are talking about here, a process called Rayleigh scattering. It is named after Lord Rayleigh, a British scientist who described the process.

Answer 6

scientist will say it is reflecting scattered rays or it reflecting the colour of the sea. Religious folks will say it is blue cos God made it so on the first day when he said "let there be light". i will say if it blue, enjoy it cos you will never know the second it will turn grey and cloudy.

Answer 7

the sky you see that is blue is the ozone layer. this layer is made by Oxygen(III) and many of this gives the blue colour.

Answer 8

we see couler because the object we look at eg a red ball absorbs every colour except the one we see, so the red ball soaks up every colour except red. in the sky, the particles f dust adn gas, etc soak up every colour except blue

Answer 9

the sky here is grey

Answer 10

Rayleigh scattering.
