why is the sky blue?

Question

did you paint it again?

Answer 1

yes i did, do u like it.

Answer 2

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Where the sunlight is nearly tangent to the Earth's surface, the light's path through the atmosphere is so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red, at sunrise and sunset.

Scattering and absorption are major causes of the attenuation of radiation by the atmosphere. Scattering varies as a function of the ratio of the particle diameter to the wavelength of the radiation. When this ratio is less than about one-tenth, Rayleigh scattering occurs in which the scattering coefficient varies inversely as the fourth power of the wavelength. At larger values of the ratio of particle diameter to wavelength, the scattering varies in a complex fashion described, for spherical particles, by the Mie theory; at a ratio of the order of 10, the laws of geometric optics begin to apply.

Individual gas molecules are too small to scatter light effectively. However, in a gas, the molecules move more or less independently of each-other, unlike in liquids and solids where the density is determined the molecule's sizes. So the densities of gases, such as pure air, are subject to statistical fluctuations. Significant fluctuations are much more common on a small scale. It is mainly these density fluctuations on a small (tens of nanometers) scale that cause the sky to be blue.

Answer 3

The sky is blue because of electromagnetic spectrum, which is radiation, and radiation is energy that travels and spreads as it goes--visible light. Radiation can be found in microwaves, X-rays, Gamma Rays, Microwaves, Infrared and Ultraviolet light. Ultraviolet light is what makes the sky blue, and the rainbow many different colors.

Answer 4

the atmosphere makes the sky blue

Answer 5

The sky had a crush on the dish - but the dish ran away with the spoon

Answer 6

because of "molecules in the air scatter blue light from the sun more than they scatter red light"

plus the atmosphere reaction...

here is a link to justify your question much better, good luck.

Answer 7

It's not always blue how about when the moon comes out

Answer 8

because most of the air is made up of water and water molecules reflect blue light.

Answer 9

the atmosphere, the gases in the air, basic science

Answer 10

Because of atmosphere.
