8 Facts about the Rainbow that are Rarely Known, Turns Out to be More Unique than We Think
YOGYAKARTA - The rainbow natural phenomenon always manages to captivate the attention of anyone who sees it. Its soft colors seem to be a small gift from nature after the rain subsides. Behind its beauty, the rainbow has a scientific explanation that is no less interesting to understand.
Well, here are various unique facts that may not be widely known about the rainbow. Curious? Check out the discussion.
8 Facts about the Rainbow that are Rarely KnownThe rainbow is an optical phenomenon that occurs due to refraction and reflection of sunlight by water droplets in the atmosphere. This process produces a spectrum of colors that we see as a curve in the sky. Quoted from Rainbow Symphony, here are 8 unique facts about the rainbow that people rarely know:
You will never reach the end of the rainbow.If you've ever imagined finding the end of the rainbow, it's not likely to happen. The rainbow depends on the position of the observer and the direction of the incoming sunlight. As you move, the position of the rainbow also changes, so the end always seems to be moving away.
The rainbow can be in the form of a full circle.From the ground, the rainbow usually looks like a half-circle. This is because the bottom is covered by the horizon. However, if you look from a height such as from an airplane, you can see a full-circle rainbow.
Rainbows are less common in winter.Rainbows are formed by the refraction of light by raindrops. In winter, very low temperatures make water turn into snow or ice. This condition inhibits the process of refracting light, so rainbows are less likely to be seen.
Double rainbows occur because light is reflected twice.Have you ever seen a double rainbow? This phenomenon occurs when light is reflected twice in a water droplet. The second rainbow is usually seen as dimmer and is on the outside of the main rainbow. Interestingly, the color order in the second rainbow is actually reversed.
Earth is the only planet with a rainbow.Until now, Earth is the only planet known to have a rainbow. This is because of the combination of consistent rain and enough sunlight. Without both factors, a rainbow cannot be formed.
Scientists believe that on Saturn's moon, Titan, there may be a blizzard of liquid methane rain, but because its atmosphere is so foggy, it is unlikely that enough sunlight passes through the methane droplets to present a rainbow.
The rainbow was considered as the path of the gods in the past.In Greek and Roman mythology, the rainbow is believed to be the link between heaven and earth. It is said that the goddess Iris (Arcus, for the Romans), who is the partner of the messenger god Hermes, uses her jug to take water and bring it to the clouds to form a rainbow. The rainbow that is formed then becomes a bridge between Mount Olympus (the home of the gods and goddesses) and Earth.
The longest rainbow ever seen lasted almost 9 hours.In 2017, a rainbow in Taipei, Taiwan, was recorded to last for 8 hours 58 minutes, from 6.57 am to 3.55 pm. This duration is much longer than the average rainbow which only lasts a short time.
No two people see the same rainbow.Rainbows have no physical existence because they are purely optical phenomena. So, if you and your friend stand next to each other and see a rainbow, you don't see an exactly the same rainbow as your friend sees. This difference occurs because everyone sees the rainbow from a slightly different point of view.
Those are 8 facts that people rarely know about rainbows. It turns out that rainbows are not only beautiful, but also contain various scientific and historical facts that are no less interesting. By knowing these various facts, now the moment of seeing the rainbow can feel more special because you understand the scientific process and myths behind its presence.
