Why Is the sky blue,truely?

Question

not just for points

Answer 1

Einstein answered this question. It has to do with the way sunlight is scattered by the molecules in the atmosphere. Blue light scatters more than red (Tyndall effect also known as Rayleigh scattering), so more blue light reaches our eye.

There is an excellent description at the website listed below (look at the cartoon and it will be pretty clear).

It is not a reflection from the ocean. And it isn't just water molecules that cause the effect.

Answer 2

Difference in absorption of light. When the sun is at the nearest point to where you are, noon, all colors are absorbed by air molecules but at different levels. Unabsorbed light just hits the earth. Blue is absorbed the most and is released in all directions, giving blue light everywhere.

At sunset, the sunlight hits the earth where you are at at a slant. Thus, more molecules are hit and alll the blue wavelength light gets lost in the high atmosphere before hitting earth ground level. whats left are the red lights absorbed and released at ground level..giving the red tint.

Answer 3

Rayleigh scattering (named after Lord Rayleigh) is the scattering of light, or other electromagnetic radiation, by particles much smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering of sunlight by the atmosphere is the main reason light from the sky is blue.

Answer 4

The sky is blue b/c the suns rays move through the atmosphere like a prism and the color emitted is blue.

Answer 5

sunlight,which appears white to the human eye,is a mixture of all the colors of the rainbow.when the sunlight passes through the atmosphere ,it scatters and spreads into all directions.the blue component of sunlight is scattered more strongly than any other component .that is why the sky appears blue............

Answer 6

Light rays that go no further into the Earth are blue in colour.

Answer 7

the refraction of light from the sun through the atmosphere is in the blue wavelength that we can see.

Answer 8

I would have told you, before my search, that it was due to refraction of sunlight as it enters our atmosphere and/or as it is interacted upon by certain types of atomic masses.

Answer 9

Sydney's right.

Answer 10

i dont realy know..
