Nature stores various mysteries from the largest to the smallest, various natural phenomena occur in this hemisphere. When the afternoon has arrived and the coincidence of the day is quite bright, there is nothing wrong if we direct the view to the western horizon. The situation will look beautiful scenery displayed by God for each of his servants, the sky is reddish orange. It's an amazing sight and often makes us more aware of how incredible the creator is. It is He Who created the heavens and the earth, day and night with all the beauty and privilege that accompanies it. But have we ever asked, is there a scientific explanation why the sky is orange or reddish not during the day? or in the afternoon?
In fact, in so simple a question many scholars do research to find that answer, scientifically answer that on the understanding why the sky on the western horizon looks orange in the afternoon before sunset. Why is that? Yes ... because when the blue and purple colors are more dissipated, the colors with small frequencies like red, orange, and yellow still move straight through the atmosphere. As a result, in the eastern hemisphere, people can no longer see blue and purple as they have spread. At that time, people in the eastern hemisphere will only see the "remains" of colors that have not been scattered. The remaining color student is a mixture of red, orange, and yellow. That is why the sky looks red when the day before sunset.
Then further explanation, As one example there are two people x and y. Each is in a different hemisphere. X is a part of the earth that experiences daylight, while Y is more east than X and therefore it has entered into the territory of the afternoon before sunset.
When the sunlight will emit a white light in a straight direction as in the distance between X and sun shorter than Y in the afternoon. At short distances, white light from the sun will experience scattering especially for blue and purple because of its high frequency. As a result, X will see that the sky is blue. But at a further distance, ie for X, he can no longer see the blue color. This is because most of the blue color has spread in the hemisphere during the day. Therefore, only red, orange and yellow are still passed to the eyes of X. That is why the effect of the afternoon colors is red or orange.
