why is the sky bule?

Answer 1

Funny, I thought it was blue. Never seen a bule sky.

Answer 2

The sky is blue becuase of all the diffraction the sunlight has to go through as it's crossing our atmosphere. There is actually a formula that describes this, though I can't recall it at the moment. Just know that as the rays get scattered, only the low wavelength light is able to get through (blue, not the other colors). The sky sometimes appears Red (like at sunset) because the sun is no long "on top" of you, but to the "side" of you. So now, it has to travel a greater distance and this also changes the diffraction angle, so Red light is seen, and not blue. Pollution also affects all of this.

Answer 3

When god was painting this world.. he painted the grass green.. the wood brown.. the snow white in a similar way he painted the sky blue. The scientific reason is given below:

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.



The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. The colours of light are distinguished by their different wavelengths. The visible part of the spectrum ranges from red light with a wavelength of about 720 nm, to violet with a wavelength of about 380 nm, with orange, yellow, green, blue and indigo between. The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision.

Answer 4

The sun gives off white light and white light is composed of 7 colors: red, orange, yellow, green, blue, indigo, violet- yes, the colors in the rainbow. When the white light reaches the atmosphere, the colors' wavelengths get scattered and the blue wavelengths are scattered the most so the sky is blue.

Answer 5

BULE???

well if ur talking about the Sky being BLUE. well it just wants to be blue cuz it likes to be blue

Answer 6

White light is composed of a spectrum of colors found in the rainbow. As the sun's light enters our earth the rays bend and the color blue in the white light spectrum is projected against our atmosphere. Therefore, we end up with a blue sky.

Answer 7

because thats the color of light that out atmosphere lets in the most. Look at Mars, that atmosphere lets in a pinkish red light. If there were oceans on Mars, they would look pink from outerspace, how cool is that?

Answer 8

umm i learned why in school but i forgot but i do know that the sky isnt blue cause of the ocean the oceans blue because of the sky lol

Answer 9

Because of the atmosphere, it is a mixture of different colours, as every substance absorbs colours, the colours they don't absorb is the colour it looks like and reflects (reflects <-> absorbs), so the mixture of the reflection of all substances in the sky is blue
at night there is no reflection, as there is no sunlight, so the colour is black, and of course, you see the reflection of the stars
