Rainbows are a breathtaking natural phenomenon that has fascinated people for centuries. In theory, every rainbow is a circle, but from the ground, we usually only see its upper half. However, when flying, it is possible to see a full-circle rainbow.
The reason why we only see the upper half of a rainbow from the ground is due to the Earth’s curvature. When sunlight enters a raindrop, it is refracted and reflected back to our eyes, creating the rainbow. However, the curvature of the Earth means that we are only able to see the upper part of the rainbow, as the lower part is obstructed by the Earth’s surface.
But when viewed from above, such as from an airplane or a mountain top, the full-circle rainbow becomes visible. This happens because, from a higher perspective, we can see the entire arc of the rainbow, including the lower half, which was previously obstructed by the Earth’s surface.
Although a full-circle rainbow is a rare sight, it is not an impossible one. In fact, full-circle rainbows have been documented in various parts of the world, including Iceland, Scotland, and the United States.
In addition to their stunning beauty, rainbows also hold cultural and symbolic significance. In many cultures, rainbows are seen as a symbol of hope, new beginnings, and good luck. They have been used in literature, music, and art to represent these themes.
In conclusion, while we may only see the upper half of a rainbow from the ground, a full-circle rainbow is possible and can be seen from a higher perspective, such as from an airplane or a mountain top. The beauty and symbolism of rainbows continue to captivate us and inspire us to look up and marvel at the wonders of nature.
