where does the blue in the sky come from?

Question

space is black so why is the sky blue
where is the cut off betwwen the two colours

Answer 1

It's called the Raman Effect. The sun's rays or radiation contains all kinds of electromagnetic waves. For example, In a rainbow you have several colors each of which has its own frequency. As the rays travel towards earth, they undergo absoption and scattering by the atoms and molecules of the gases (ex: oxygen, nitrogen, carbon dioxide etc.) present in the atmosphere above the surface of earth. During this process the atmospheric molecules absorb most frequencies, but scatter the frequency corresponding to 'blue light'. When an atom or molecule absobs energy from the rays, they go into an unstable excited state and eventually fall back their restful state emitting electromagnetic radiation. In doing so, it degrades the frequency of the incident light to that of blue light. That's why you see the sky is almost always looks blue.

Answer 2

The blue colour comes from the sunlight.

Answer 3

Simple, the result of expert German engineering

Answer 4

Atmosphere

Oxygen......etc

Answer 5

its called scattering i forgot how it happens but that's the reason:)
