why the sky and sea is blue in colour ?

Question

we can see the sea and the sky is blue colour but actually cant tell why, and after the sky is space and black colour....

Answer 1

actually this question is hard to explain here, well
the sky is not blue, as you see it black in night,it's because the light of sun we see it blue when sun's light enters the atmosphere, it breaks(i'm not sure of the scientific name) this is exactly like when you shed a light in a glass or when you put your pencil in a glass of water(not completely vertical),that's becase speed of light is different in different surfaces,)but sun's light cosist 7 colors that you see in rainbow(rainbow also formes of the same reason)and each color breaks differently,purple breaks the most(it become nearer to the vertical line) hen blue ....and red.
and when sun's light come into atmosphere we see it blue.so where does red go? to the other side of the earth where su is going down! in sunset we see the red light and the sea also reflects the sky ;)

Answer 2

The sky is blue because blue light from the sun is scattered in the atmosphere. The sea just reflects the sky's colour

Answer 3

colour is just the way in which we perceive light reflecting off different substances, and your relative position. Go 200m into the sea it's black. The sky looks blue because of the light reflecting off the atmosphere. The best way to think of it, sticking with the nautical theme is if you see a a seagull against a bright sky a long way off it will look black, if its hopping about on the bonnet of your car it's white. It's all a matter of perspective and the perception.

Answer 4

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 5

I am sure the in sea parts the sky is more blue , I mean the sky is in all the parts blue but this part is more blue ,
as one of the answerer's said the color of sea and water make the color of sky , but now the sky is not as blue as many years ago , and that's of air pollution

Answer 6

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. Similar for the sea...

Answer 7

I think you'll find it's to do with the reflection of the sun light bouncing off of the sea up to the clouds and back again. Then the light that does not hit the clouds reflects of the atmosphere that is dark. The two reflecting coulours back onto the sea make different colours of the blue/green /grey spectrum.

Answer 8

the sky is blue because the present ratio of gases in the atmosphere absorb more blue wavelengths than other colours making the sky appear blue.

The sea is just a reflection of this.

when the sky is grey the sea appears grey also.

billlions of years ago the atmosphere was rich with methane making the sky appear green.

space appears black because there is no light betwwen the stars hence no wavelengths of colour

Answer 9

You see, the sun shoots out light. Light has many different colors in it, like the rainbow. When the light hits a certain layer of substances up above us, it scatters due to the different things that are there.
Most other colors of light bounce away because they are too "big" to get past the substances, but blue light is "small" and thin, and can get past the substances. Since it gets past those, it makes the atmosphere look blue, which is why we say that the sky is blue.
Water is transparent in reality, as we all know, but the blue light above large bodies of water causes the water to reflect the light. In doing so, it looks to us like the water is blue as well.

Answer 10

the sky is surrounded by gasses so to it looks blue when it gets the sun shines on the gas called ozone layer its blue from all the fumes and stuff that we burn but when it gets dark it changes because there is no light to shine on the ozone so it becomes clear and we can see the stars and other systems
the sea seams blue as it the reflection from the sky in different countries but if you cancelled the blue and changed it to yellow the sea shall become yellow
