5A Rainbow As Seen From a Plane

When you see a rainbow it looks like its name suggests, a bow. However, when seen from great height it appears as a circle. Therefore there’s no end to it and no gold. Rainbow is an optical-meteorological phenomenon that has attracted people’s attention since ancient times. People have long ago called this phenomenon a magical phenomenon, or by associating it with religion because they were unable to explain it. The explanation of this phenomenon of nature dates back to the 1700s by the Brazilian physicist H. Moyses Nussenzveig, in 1900 by the Brazilian physicist H. Moyses Nussenzveig, and then by a more scientific explanation by scientist Warren Wiscombe in 1980. The phenomenon of rainbow, as mentioned above, is an optical-meteorological phenomenon that appears in the atmosphere immediately after rain. In order for the rainbow to be visible to the human eye, it is necessary for the person to be placed between the sun and the rainbow, which appears in the part where it is still visible, which symbolizes the raindrops emanating from the sun’s rays in the clear sky. his phenomenon is nothing but the refraction and reflection of sunlight by the water pier in the atmosphere. We often see two rainbows at a time, and this has to do with the double reflection of the sun’s rays from the many points of water in the atmosphere. This is related to the angle of reflection of the sun’s rays because the rainbow is nothing but the reflection of the sun’s rays in our eyes. Thus, if the angle of incidence of the sun’s rays gradually increases, the rainbow we see will decrease, until it disappears. We can also see the rainbow as a complete circle with its 7 colors (purple, red, orange, yellow, green, blue and violet) where in addition to the above conditions we must be at high altitude or from the plane, based on the above physical explanation.
