Sunlight interacting with the Earth's atmosphere makes the sky blue. In outer space the astronauts see blackness because outer space has no atmosphere.
Sunlight consists of light waves of varying wavelengths, each of which is seen as a different color. The minute particles of matter and molecules of air in the atmosphere intercept and scatter the white light of the sun. A larger portion of the blue color in white light is scattered, more so than any other color because the blue wavelengths are the shortest.
When the size of atmospheric particles are smaller than the wavelengths of the colors, selective scattering occurs-the particles only scatter one color and the atmosphere will appear to be that color. Blue wavelengths especially are affected, bouncing off the air particles to become visible.
This is why the sun looks yellow from Earth (yellow equals white minus blue). In space, the sun appears white because there is nothing in between to scatter its white light.
At sunset, the sky changes color because as the sun drops to the horizon, sunlight has more atmosphere to pass through and loses more of its blue wavelengths. The orange and red, having the longer wavelengths and making up more of sunlight at this distance, are most likely to be scattered by the air particles.
The scattering of visible light by atmospheric gases is most correctly called the Tyndall effect, but it is more commonly known to physicists as Rayleigh scattering after Lord Rayleigh, who studied it in more detail a few years later. Rayleigh Scattering is where red, orange, yellow, and green are passed through and blue, indigo, and violet are "scattered" out creating the color.
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 for why the sky does not appear violet -- the wavelength most scattered -- see the explanation at the related link below.)
Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
The sky appears blue to us because of the scattering of the blue light component of the light from the Sun. Some alpine lakes also appear a quite light blue colour for the same reason, light is scattered by tiny suspended flakes of minerals in the water.
Because the water particles in the air split the light and Blue light is dispersed the furthest that's why it creates the illusion the sky is blue

Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

When the Sun's light reaches the Earth's atmosphere it is scattered, or deflected, by the tiny molecules of gas (mostly nitrogen and oxygen) in the air. Because these molecules are much smaller than the wavelength of visible light, the amount of scattering depends on the wavelength. This effect is called Rayleigh scattering, named after Lord Rayleigh who first discovered it.When the Sun's light reaches the Earth's atmosphere it is scattered, or deflected, by the tiny molecules of gas (mostly nitrogen and oxygen) in the air.

Shorter wavelengths (violet and blue) are scattered the most strongly, so more of the blue light is scattered towards our eyes than the other colours. You might wonder why the sky doesn't actually look purple since the violet light is scattered even more strongly than blue. This is because there isn't as much violet in sunlight to start with, and our eyes are much more sensitive to blue.
The blue light that gives the sky its colour, is sufficiently bright to make all the stars that we see at night disappear since the light they emit

What are some of the big, or small, questions that we still need to research more in your field? Or just problems that still need to be solved. Whether in particle physics or condensed matter physics and whether basic or applied fields or anything in between. And how does the work that you are doing help us get closer to answering those questions (if you are working in such a direction)?

Due to Electromagnetic radiation being scattered by the Earth's atmosphere and the inverse proportionality of light's wavelength and frequency. The light that's scattered by our atmosphere is red and blue.

The sky is blue because the sky is really clear and when the sun shines on the ocean it reflex back to the sky so it makes it blue

Thus, as sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. ... More of the sunlight entering the atmosphere is blue than violet, however, and our eyes are somewhat more sensitive to blue light than to violet light, so the sky appears blue.

The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength. ... These shorter wavelengths correspond to blue hues, hence why when we look at the sky, we see it as blue.

The sky is blue because of light rays reflecting off of Earth's water. The rays bounce off of the water, and carry the blue color with them, where they then bounce off of particles of our atmosphere's air, thus, the blue color is produced.

Because of seals back then seals were microclinis that affect our earth then those microclinis got close to earth then earths gravity pulled them closer while they were making there way to earth they left a trail of what is know is sky when they came to earth microclinis collided with encylicalsgy then it made like it seals

Why is the sky blue at daytime?
because the the oceans color is reflected into the sky
Why is the sky and water blue?
The sky is blue because of Rayleigh scattering -- blue photons scatter off air molecules to a large extent, while the other colors travel directly in straight lines from the sun, making the sky appear blue and the sun appear yellow (white minus blue). In space, or on the airless moon, the sky is black and sun is white. It is NOT true that oceans look blue due to sky reflection. Water also scatters blue light, so the explanation of its color is largely the same as that for the sky.
Is the sky blue a hypothesis?
No. The sky is just as blue as a blue shirt though. Technically an object, such as a shirt or the sky, is not blue. The object just appears to be blue because it absorbs all other colors of the spectrum and reflects blue back which is the same with any other color seen.
Why is the sky blue and the grass green?
The grass is green because it has the green pigment clorophyll like most other green plants and I do not know why the sky is blue
Why the water appear sky blue at beaches and dark blue in ocean?
It's because the water is deeper.
Why the sunset is sky blue?
because the sky is blue
Is the sky blue because the sea is blue?
No, the sky is not blue because the sea is blue. The sea water is actually clear, not blue, so we can automatically rule out that the sky is blue because the sea is blue. However, if you see the sea as blue, then it's more correct to say the sea is blue because the sky is blue.
Is the sky blue because of chemical reactions?
No. The sky is blue due to the scattering of light.
Is the sky blue due law of parody?
No i think the sky is blue because the reflection of the ocean or could it be the sky is blue and it reflects on to the ocean?
What does sky blu look like?
The color sky blue is a lighter shade of blue. The color is called sky blue because it is to resemble to same color as the sky. When the sun is out the sky is a beautiful shade of blue.
why is the sky blue in color?
Because the ocean reflect to the sky .
Why the sky seems blue be to you?
the sky seems blue to us, because the suns rays reflect off the earths atmosphere and it produces the sky to be blue.
Bluecolor of sky is because of the phenomenon of?
The sky is blue because various constituents of the atmosphere scatter light selectively, leaving the blue color. The sea is blue because of the same reason, not because of the reflection of the sky. If the sea isn't blue, it is because of plants/bacteria that live in the water and disscolour it.
Can youdescribe the sky?
The sky is blue because particles in the air only reflect blue light rays
What is the superstitious belief of why the sky is blue?
the sky is blue because its means that the sun will raised and we have a good weather
Is the sea blue or is it the reflection of the sea?
The sea is blue because it reflects of the sky so when the sky is blue the sea is blue and when the sky is grey the sea is grey. hope this helped ashley

The sky isn't yellow because it is blue!!!! HA!
