Rainbows are the arcs of light that grace the sky after a rain shower. They are optical illusions created by the sun, rain, and your eyes. Rainbows form when sunlight strikes the raindrop at the right angle. They have captivated humanity for centuries. Their beauty has inspired poets, artists, children, and dreamers across cultures and time periods. Beyond their colors and beauty, they hold scientific explanations. Here’s the fascinating trivia and fun facts about the rainbow.
Rainbows are unique and we don’t get to see them every day. Everyone, regardless of age, wishes to see a rainbow for its colors and uniqueness. They are just more than just pretty sights; they are the finest products of light and water. When sunlight encounters raindrops, it undergoes a process called refraction. As light bends and enters the water droplet, it splits into multiple colors – red, orange, green, blue, indigo, and violet. These colors are then reflected and emerge at different angles, creating the rainbow we see in the sky. This explains “how are rainbows created.” Rainbows are appealing to everyone including children.
The word “rainbow” comes from the Old English word “regenboga,” which means “rain bow.” The earliest recorded use of the word dates back to the 13th century.
The average duration of the rainbow is less than 60 minutes but in rare occasions, it may prolong. The longest rainbow ever recorded was in Taiwan, China, at 8 hours and 58 minutes in 2017 by a student and professor at a Chinese Culture University. While you are reading this, we’d like you to know the smallest measurement of time ever recorded.
We can see the complete shape of the rainbow when flying in an airplane, while people on the ground can only see the semi-circle. A ‘glory’ is a full-circle rainbow. It is an optical phenomenon that looks like small, circular rainbows of interlocking colors. This answers the questions “how are rainbows formed.”
There are a total of 7 colors. the raindrops reflect at an angle of 40 degrees for the red light and 42 degrees for the blue light.
With the resources and scientific technology, we have studies that prove that rainbows are common only on planet Earth. There is no other planet that has enough water in its atmosphere to cause rain. Now this makes me wonder if cloud seeding is possible in other planets.
Interestingly, it is not the same for everyone. Even two persons standing parallel cannot see a rainbow in the same way the other person sees it. This is due to the fact that a rainbow has no physical presence, it is a purely optical phenomenon and its appearance. Its precise shape, arc, and width of its color bands will vary slightly.
According to kids in kindergarten, the rainbow is a beautiful arc of colors that appears in the sky after a rain shower. Kids often encounter rainbows in their coloring books rather than in reality.
Rainbows continue to inspire us for their captivating blend of science and beauty. They are a reminder of nature and the power of light to transform the ordinary into something extraordinary.
