Why is the sky blue?

Answer 1

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 2

I think that there is term scattering involved because there are different types of coloured light in the sky, red, purple, and blue. These coloured particles separate in the sky, showing all the colours. Blue is the colour that seprarate most, so the sky is blue. At the end of the day, the blue particles slowly vanish, which is why the sunset is a different colour :D

Answer 3

The sky is blue due to the effects of Rayleigh scattering. which is the scattering of sunlight by particles in the atmosphere that are smaller than the wavelength of the light. Because blue has a smaller wavelength than red or green, the sky appears blue. Remember the acronym for electromagnetic spectrum, ROY G. BIV, (Red, Orange, Yellow, Green, Blue, Indigo, Violet).

Answer 4

The sky is blue because the particles in suspension in the atmosphere mainly reflect this color (from the large spectrum of solar light). In fact, if you go on the Everest at nearly 9 thosands of metres above sea level, tha sky will appear darkest than at sea level, because the density of suspended particles is lesser on the Everest han at sea level. If you go at 200 kms above sea level, the density of particles is so low that the sky appears dark.

Answer 5

If you look at liquid oxygen, it is a Blue colour.

This was demonstrated on a (UK) TV programme called Tomorrows World aired back in the 1980's where they had discovered that Oxygen is effected or attracted by magnets.

What happened was they had a rig with powerful electro magnets with a small gap, they powered them up and then poured liquid Oxygen into the gap between the magnet nodes and the Oxygen was attracted to either poles and was suspended while it evaporated, the colour of Oxygen was.... BLUE.


Additional.... This is also how Scenic fiction all of a sudden turned away from Air locks to "Magnetic Air locks".... as seen in films like Starwars.

Answer 6

Sky's blue when you appreciate things in its beauty. It's pathetic to see that in some areas you seldom see it anymore because of the smog.

Answer 7

Nuclear fusion makes the stars to shine
Tropism makes the ivy twine
Rayleigh scattering makes the sky so blue
And testicular hormones mean - - -.

Answer 8

A simple explanation would be "Tyndall Effect" which gives the blue color.

The Tyndall Effect is caused by reflection of light by very small particles in suspension in a trasnparent medium. It is often seen from the dust in the air when sunlight comes in through a window, or comes down through holes in clouds. It is seen when headlight beams are visible on foggy nights, and in most X-File episodes when Moulder and Sculley check out some dark place with flashlights.

Answer 9

sky is blue >>> becoz of the phenomena called refraction and this is also the reason we see water on dry land in a hot summer day

Answer 10

It's the way the atmosphere filters light from the sun that causes the blueness.
