why is the sky blue?

Question

why is the sky blue sometimes.....how did it get that way?

Answer 1

because it wants to be gosh

Answer 2

The Sun's white light is composed of all the colors of the rainbow, from violet and blue to red. Violet and blue have the shortest wavelengths, and red has the longest wavelength.

When sunlight enters the atmosphere, some of the light is scattered by the molecules in the atmosphere and tiny bits of dust in the air. Because blue light has the smallest wavelength, it is the most likely to be scattered by these tiny objects.

So the blue of the sky is sunlight that has been scattered by the air.

Answer 3

Same reason that it was the last 50 times this question was asked in the past 2 weeks -- the Tyndall Effect.

It "got that way" because the sun came up. During the night, it was black with tiny white flecks.

Has anyone ever searched for an answer before asking the same question over and over again?

Answer 4

The refraction on the upper atmposphere, where since blue and violet are the shortest wavelengths, and our eyes are more sensitive to blue, we perceive the sky as a bluish color.

Answer 5

Light passing through oxygen absorbs all but the blue rays. Nitrogen is way more abundant in the atmosphere, but it is non reactive to light. The red color you see in the evenings is usually dust particles in the air.

Answer 6

The sunlight is filtered through the various gasses of the atmosphere, which turns the atmosphere blue upon illumination.

Answer 7

It is covered by ozone gas. The gas allows to pass only the blue colour

Answer 8

Because the atmosphere is blue.

Answer 9

because blue is the only color reflected while the other colors of the rainbow are absorbed.
