when sunset comes how does the sun turn red or orange?

Answer 1

It is due to scattering of photons, where colors of shorter wavelengths (such as blue) are reflected and refracted by air particles when passing through the atmosphere in a longer path during sunrise and sunset.

In contrast, the light path during noon is comparably shorter. Therefore more colors can pass through without being scattered, thus a more even spectrum can be observed during noon.

Wikipedia has many articles about this process, but most of them are poorly written and referenced.

Answer 2

As the sun moves closer to the horizon it has to travel through more atmosphere than when it is overhead. Also any pollutants or water particles will also affect our perception of the sun light. Some of the most spectacular sunsets occur when there's some smog because if shifts the light toward orange/red/purple.

Answer 3

Red light has longer wavelengths. So when the sun sinks low on the horizon, the other visible light waves (non-red) get blocked by the atmosphere but the red spectrum is still able to pass through to the ground, thus making the sun appear red or orange.

Answer 4

This has to do with light scattering as the sun moves towards the horizon. To see the sun, you have to look through more of the ground-level sky, and the particulates in the sky cause the color of the sun to shift.

Answer 5

Something to do with the angle and the wavelengths

Oh unless you mean the actual sun..I was thinking of the sunlight.
I'm pretty sure it's the atmosphere

Answer 6

the particles in the air make the sun, or moon for that matter, look different colors.

Answer 7

its because thats its true coler when it gets closer you see it in vision better
