A Double Treat!

“Somewhere over the rainbow,
Skies are blue,
And the dreams that you dare to dream,
Really do come true.”
~E.Y. Harburg~

The world is full of beautiful things…some say it’s lucky to spot a rainbow in the sky, but have you been fortunate enough to ever spot a double rainbow??

🌈A double rainbow is a natural wonder  where you can spot spectacular displays of two rainbows simultaneously.
🌈The lower, brighter rainbow is the primary rainbow and the higher, fainter one is the secondary rainbow.

🌞A double rainbow is formed when sunlight is reflected twice in a drop. That means you can see two different reflections coming from different angles.

Primary Rainbow: Is the first and brighter rainbow with red as the outermost color of its arc, and violet as the innermost color.

Secondary Rainbow: Is the second and fainter rainbow with its color sequence inverted to the primary one with red is on the inside of the arc and violet on the outside. It is lighter and more pastel because refracted light bounces of the raindrop not once but twice. It is also twice as wide as the primary rainbow as it is dispersed over a wider area of the sky.

This optical phenomenon is known as Alexander’s band after Alexander of Aphrodisias who first described it in 200AD.

Double rainbows aren’t as rare as they may seem. They are generally spotted when the sun is low in the sky (early morning or late afternoon).

In some eastern cultures a double rainbow are considered to be auspicious and symbolize spiritual transformation where the first arc represents the material world, and the second arc, the spiritual realm.
