FACTS ABOUT RAINBOWS
Even though rainbows figure prominently in the myths and religions of so many cultures throughout history, no one had any idea what the heck they actually were until the 17th century.

5. The Greek epic poet Homer believed that rainbows were made of a single color, purple. (How decidedly unpoetic.)

In 1666, Isaac Newton added indigo and orange to give us the seven-colored Roy G. Biv that we all know and love today. However, in China rainbows are considered to contain just five colors.

Double rainbows occur when light bounces inside the water droplet more than once before escaping, the spectrum of the second arch will be reversed. Sometimes third or fourth rainbows can be seen.

The world’s longest-lasting (or longest-observed) rainbow was seen over Sheffield, England on March 14, 1994 – it lasted from 9am to 3pm. (If there were ever an opportunity to secure a pot of gold...!)

The truth is, there is no set number of colors in a rainbow! Each hue blends into the next without a hard boundary, leaving the interpretation up to the person who sees it and the culture that has defined it. (I'm going with 28 colors, so there.)

12. And in fact, a rainbow doesn’t even actually “exist,” ... it’s not an object, it’s an optical phenomenon. Which is why no two people see the same rainbow.

It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

Answer 2

Answer:

A rainbow is a natural phenomena which occurs by the refraction, reflection and dispersion. It occurs when both rain and sun are present in the sky simultaneously.
