Where Does the Green Go at Twilight?

    Green
In summary, during twilight the sun's light is scattered and travels through a longer path in the Earth's atmosphere, causing the sky to appear red due to the longer, red wavelengths being more visible. This lack of green at twilight is a natural phenomenon and is not caused by pollution. It is a result of the scattering of sunlight in the atmosphere, which affects the color and intensity of the sky's colors. This phenomenon can be observed in all parts of the world, and its duration varies depending on location and time of year, typically lasting 20 minutes to an hour.

Why is no green color on the sky at twilight??

Maybe you are not looking hard enough or maybe you are not looking at the right time at the right angle. I HAVE seen a horizontal trail of green, although this was at dusk, in the east sky. The stength of this green was not very strong, but it was recognizable.

Why is this intensity so low? In the rainbow the green's intensity is much greater.
 

1. Why does the sky turn red at twilight?

During twilight, the sun's light is scattered and travels through a longer path in the Earth's atmosphere. This causes the shorter, blue wavelengths of light to scatter more, leaving the longer, red wavelengths to be more visible, giving the sky a red appearance.

2. Is the lack of green at twilight caused by pollution?

No, the lack of green at twilight is a natural phenomenon caused by the scattering of sunlight in the Earth's atmosphere. Pollution may affect the color and intensity of the sky's colors, but it is not the sole cause of the lack of green at twilight.

3. Why is there a lack of green at twilight but not during the day?

During the day, the sun's rays are more direct and have a shorter path to travel through the atmosphere. This allows for the shorter, blue wavelengths to be more visible, giving the sky a blue appearance. However, during twilight, the sun's rays are scattered and travel through a longer path in the atmosphere, making the longer, red wavelengths more visible and giving the sky a red appearance.

4. Can the lack of green at twilight be seen in all parts of the world?

Yes, the lack of green at twilight is a natural phenomenon that can be observed in all parts of the world, as long as there is a clear view of the horizon and the sun is setting or rising.

5. How long does the lack of green at twilight last?

The duration of the lack of green at twilight can vary depending on the location and time of year. On average, it can last anywhere from 20 minutes to an hour, with the colors gradually changing as the sun continues to set or rise.
