You have probably seen an actual rainbow. But do you know how are rainbows formed?
An optical and meteorological phenomenon, a rainbow is caused by reflection of light in water droplets in the planet’s atmosphere, resulting in a spectrum of light appearing in the sky. A rainbow takes the form of a multicolored arc.
Rainbows that are caused by sunlight will always appear in the section of sky that is directly opposite the sun.
There is an old legend that at the end of the rainbow, you will find a pot of gold. However, the rainbow is not located at a specific distance, but a result of the water droplets viewed from an angle relative to the sun’s rays. So the rainbow is not an object and therefore cannot be approached physically.
Rainbows can be caused by various forms of airborne water. These include not only rain, but also mist, spray, and airborne dew. By dispersing water droplets into the air (say, using a hose) during a sunny day can also produce a rainbow effect. The rainbow effect is also seen commonly near fountains and waterfalls.
Rainbows have become a significant part of human culture. They occur in many cases in mythology, and have been used in the arts.
