why is the sky blue?

Question

NOTHING ON WIKIDEIA.COM!!!!!!!!!!!!!!!!!!!!

Answer 1

actually the sky is colorless but the color of few gases (exactly i don't remember now..sorry for that) as we can see the dark sky in night. the same color scheme applied here we see flowers are red in day time and in night we cant see them. so as well as sky looks blue in day time and dark in night.

Answer 2

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. As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.

Answer 3

For the same reason Hawaii has a interstate highway. However, the best guess is:Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. 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.

Answer 4

Because it isn't -- it's clear/transparent.. which is why you can see stars & planets etc. at nighttime.

By day, the particles reflect a blue hue from miles & miles of layers (assuming there's no clouds!). It's what's comprised in the gaseous layers that reflects blue from our perspective, by day. The air by the way does NOT reflect the oceans... it reflect/bounces back LIGHT and shows/like a prism the hue of what light looks like having passed through it to the human eye... is all.

Answer 5

The molecules of air and other fine particles in the atmosphere have size smaller than the wavelength of visible light. These are more effective in scattering light of shorter wavelengths at the blue end than light of longer wavelengths at the red end. The red light has a wave length about 1.8 times greater than blue light. Thus, when sunlight passes through the atmosphere, the fine particles in the air scatter the blue color more strongly than red. The scattered blue light enters our eyes.

Answer 6

The blue sky is the reflection of the oceans in the atmosphere.

Answer 7

the sky is blue due to reflection of water vapours in white light.

Answer 8

Due to atmospheric refraction. another reason can be dispersion of white light into seven colours. other colours are absorbed but blue is reflected

Answer 9

because most of earth 's surface is water , so water .. so water reflects the color .. and the sky looks blue

Answer 10

the ski is blue because light reflects off the ocean and back up
