Facts About Rainbows

Are you curious to learn some weird and wonderful facts about Rainbows?

If so, excellent! You are in exactly the right place my friend…

It’s time to chat about Rainbows facts.

Let’s dive right in…

1 – The colors in a rainbow are red, orange, yellow, green, blue, indigo and violet.

2 – The order of these colors is commonly remembered using this acronym: ROY G BIV (red-orange-yellow-green-blue indigo-violet). This is a handy reminder to remember the color sequence in a rainbow.

3 – A rainbow is a natural optical phenomenon that occurs when the sun shines on droplets of water in the Earth’s atmosphere.

4 – Rainbows typically occur in the morning or late afternoon because of the sun’s position.

5 – An average rainbow spans about 150 feet across in length and 20 degrees in width but this varies depending on where the observer is standing relative to the storm cloud or water droplets from which it was created.

6 – It takes about 10 minutes for a rainbow to form after the rain has stopped falling. Most rainbows last for 10-20 minutes before they fade.

7 – A full circle rainbow is called a double rainbow because it appears to have an extra band on either side of the main bow.

If you see a double-rainbow it means you’re witnessing two separate bows created by light reflecting off of both sides of one cloud at exactly opposite angles to your eye.

8 – Red has the longest wavelength and violet has the shortest wavelength of all visible light.

9 – A rainbow can be seen up to 100 miles away from the original source of light (the sun). The most common type of rainbow is called an arc-shaped one because its top looks like an “arc” rather than a complete circle.

10 – The word “rainbow” comes from Old English words meaning “to make bright.”

11 – The first person to link rainbows to good fortune was Saint Augustine of Hippo.

12 – Rainbows are formed by light refracting through water droplets.

13 – There are actually two types of rainbows – an “inner” or “primary” rainbow, which is made up of only light refracted by water droplets; and an “outer” or “secondary” rainbow, which is caused by both sunlight and moonlight reflected from water droplets.

14 – Rainbows can be seen anywhere there’s a source of water or moisture in the sky (like fog or mist) but they’re more common near mountains since that’s where most rainfall occurs.

15 – The image of a rainbow is created by light that has been refracted or dispersed into its different component wavelengths.

16 – Rainbows typically do not form on clear days due to lack of moisture in the atmosphere.

17 – A rainbow is only visible from the ground to an angle of 42 degrees, which means it can’t be seen very far away or high up in the sky.

18 – There are three types of rainbows – primary (red on outside), secondary (green on outside) and tertiary (blue on outside).

19 – In Ancient Greece rainbows were believed to be a sign from God or Zeus as they were often seen after battles or other disasters.

20 – It’s impossible to capture all the colors in one photo because there are so many different wavelengths of light.

21 – The first mention of rainbows was found in ancient Chinese texts dating back to 1100 BC.

22 – Indigenous Australians believe that rainbows were created by spirits drawing with their fingers across the sky as they traveled from one end of Earth’s horizon to another.

23 – If it rains outside while there’s a full moon out at night time then it causes an eerie phenomenon known as “moonbow.”

24 – When raindrops hit the ground they form circular patterns called “rainbow circles” or “mackerel sky” which can be seen from above when viewed from below.

25 – The most common type of rainbows are called “natural” rainbows – these happen when light enters water droplets through one side and leaves through another.

An inverted natural rainbow is called an anti-rainbow because it happens when light enters water droplets on one side but cannot exit due to the shape of the droplet.
