Once in the previous section we examine why the sky is blue, we will now try to develop a study of "why the sky in the western horizon appears orange when the afternoon before sunset?" This issue still has to do with the study of the blue sky in the afternoon Before this is known that, during the day when white light passes through the atmosphere, the white light will experience scattering. That is, blue and purple light (because it has the highest frequency among other colors) will be dissipated more than red, orange, and yellow. The question is, then what happens with the red, orange and yellow? How is his fate this will lead us to the understanding why the sky in the western horizon appears orange in the afternoon before sunset. Why is that? Yes ... because when the colors of blue and purple 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 are no longer able to see blue and purple because they have been scattered. At that time, people in the eastern hemisphere will only see the "remains" of the color that has not been scattered. The remaining color student is a mixture of red, orange, and yellow. That is why the sky appears red when the afternoon If the afternoon has arrived and the coincidence of the day is quite bright, it would not hurt if we direct the view to the western horizon. A beautiful scene is being shown by God for each of His servants, the sky is orange reddish. What 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 any scientific explanation why the sky is orange when the afternoon But do not forget, after we see the beautiful western horizon in the afternoon, immediately take the water wudlu, come to the mosque, we glorify the greatness of God. Hopefully useful The sun will radiate white light in the straight direction as in Figure 1. The distance between A with the sun is shorter than the B that had entered in the afternoon. At such a short distance, the white light from the sun will experience scattering especially for blue and purple because of its high frequency. As permisalan there are two people A and B. Each is in different hemisphere. A is in a hemisphere that is experiencing daylight, while B is further east of A and hence it has entered the afternoon This event, as discussed earlier, causes A to see that the sky is blue. But at a further distance, ie for the B, he was no longer able to see the blue color. This is because most of the blue color has been scattered in the hemisphere during the daytime. Therefore, live red, orange and yellow are still forwarded to the eyes of B. That's why, why the afternoon sky tend to orange reddish color.
