how can you prove that sky is blue?

Answer 1

Good gawd! Once again, none of you "science" people understood the question.

There are a number of ways to prove the sky is blue. You can get it into a counselor's office and start discussing all the depressing aspects of existing above a bunch of polluting pigs. You can get it drunk and just listen. You can show it some sad movies, and observe how it identifies with the depressed characters. My trick would probably be to take it to an R&B lounge, and let it listen to some good music for awhile. There's nothing like listening to the blues to help you show your feelings to the world.

The trouble is, the sky has an immense responsibility, and it doesn't get much appreciation from us, so it's not hard to see how crummy it feels.

Answer 2

Who said there is a sky. Our senses are very limited as whatever we are seeing around may not we true.whatever we see above our heads, looking blue, is not sky as most of the children and thier parents believe. Nor even it can be said that sky is far above. As much high we will move in the sky we will find no surrounding roof. But scientifically it is impossible to have a hight without its upper end. Then where is sky? And where is the uppermost point of the universe. Truely we will remain at the conclusion that man is made much limited, even in his knowledge.

Answer 3

By looking at the sky.
And if you want the technical answer it is as follows. As the light is made up of different colours the angle at which the sunlight hits the water creates the the blue light difraction in sky so we see he sky as blue.

Answer 4

Sky seems blue from the earth.

Answer 5

It stands proved that sky is blue why you want to get the same thing to be repeated.the basic thing is that this is because of rays of light.

Answer 6

actually the sky is not blue at all it may appear blue due to the scattering of light rays from the sun here blue light is the most scattered therefore the sky appears blue

Answer 7

You need to give more information. Why and to whom do you need to prove the sky is blue?

Answer 8

Why is the sky blue?

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Combined, these effects scatter (bend away in all directions) some short, blue light waves while allowing almost all longer, red light waves to pass straight through. When we look toward a part of the sky not near the sun, the blue color we see is blue light waves scattered down toward us from the white sunlight passing through the air overhead. Near sunrise and sunset, most of the light we see comes in nearly tangent to the Earth's surface, so that 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.

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.

Why is the sky blue instead of violet?

Because of the strong wavelength dependence (inverse fourth power) of light scattering according to Raleigh's Law, one would expect that the sky would appear more violet than blue, the former having a shorter wavelength than the latter. There is a simple physiological explanation for this apparent conundrum. It turns out that the human eye's high resolution color-detection system is made of proteins and chromophores (which together make up photoreceptor cells or "Cone" structures in the eye's fovea) that are sensitive to different wavelengths in the visible spectrum (400 nm–700 nm). In fact, there are three major protein-chromophore sensors that have peak sensitivities to yellowish-green (564 nm), bluish-green (534 nm), and blue-violet (420 nm) light. The brain uses the different responses of these chromophores to interpret the spectrum of the light that reaches the retina.

When one experimentally plots the sensitivity curves for the three color sensors, three roughly "bell-curve" distributions are seen to overlap one another and cover the visible spectrum. We depend on this overlap for color sensing to detect the entire spectrum of visible light. For example, monochromatic violet light at 400 nm mostly stimulates the S receptors, but also slightly stimulates the L and M receptors, with the L receptor having the stronger response. This combination of stimuli is interpreted by the brain as violet. Monochromatic blue light, on the other hand, stimulates the M receptor more than the L receptor. Skylight is not monochromatic; it contains a mixture of light covering much of the spectrum. The combination of strong violet light with weaker blue and even weaker green and yellow strongly stimulates the S receptor, and stimulates the M receptor more than the L receptor. As a result, this mixture of wavelengths is perceived by the brain as blue rather than violet. Simply put, the human visual system is not good at detecting violet light when other wavelengths are present, and so the sky appears blue rather than violet.

Answer 9

Who said that the sky is blue? The color of the sky is black. It is the reflection from our Earth's water bodies.

Answer 10

First of all the sky is not blue! It "appears" blue because of the scattered blue rays from the air molecules
