why is the sky blue?

Answer 1

cause i have blue eyes and it reflects my eyes duh

Answer 2

During daylight the sky has the appearance of an opaque blue surface, but this is the result of the air scattering sunlight.

The color of the sky is a result of diffuse sky radiation. On a sunny day the Earth sky usually looks as a blue gradient — dark in the zenith, light near the horizon (due to Rayleigh scattering). It turns orange and red during sunrise and sunset, and becomes black at night.

Answer 3

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.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

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 4

Many people think they know the answer to this question but actually they don't. The correct answer is that the Sun's light is white light and white light is made up of all the colours in the electromagnetic spectrum (Green, Red, Orange, Indigo, Blue, Yellow and Violet). The white light is scattered by the air particles and Blue and Violet are scattered most. The human eyes aren't sensitive to Violet light so you see mainly BLUE.

Answer 5

The sky is blue because refracts off water vapor, making the sky appear blue.

Answer 6

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 7

Sky is nothing but a atmosphereless vacuum. Our eyes response to vision is limited. Light gets refracted and only blue shade is visualised with our eyes from long distance.

Answer 8

light is reflected in the shade of blue, red, or purple

Answer 9

take a look at my page.i have once answered such a question and it is available in my page. good luck

Answer 10

because if it were any other color it wouldn't be blue.

Answer 11

coz blue is cool..
