Why National Find a Rainbow Day?
The National Find a Rainbow day is lesser-known and celebrated on the early spring season. Seeing a colorful rainbow adds more color to our day.
A rainbow is a Phenomenon caused by reflection, refraction and dispersion of light in water droplets eventually resulting in spectrum appearing in the sky.
Rainbows appear directly opposite to the sun. Normally the outer part and the inner part of the rainbow will be of red and violet colors respectively.
How we can Celebrate or Observe Find a Rainbow Day:
Let us celebrate this day by posting our pictures taken anywhere at any time with the rainbow using this hashtag #RainbowandMe, #NationalFindARainbowDay, #FindARainbowDay on Twitter.

Interesting Facts About Find a Rainbow Day:
We may not aware of the various rainbows appears in the sky which includes
- Multiple rainbow, which appears due to the double reflection of sunlight into the water droplets, thus appears the Primary bow and a secondary bow. Since the secondary bow is “up” to the viewer, the colors appear apparently as vice versa to that of the primary bow. The gap between the primary bow and the secondary bow being called as “Alexander band”
- Twinned rainbow, which appears as just two rainbow arcs with colors in the same order. This happens due to different size of water droplets being reflected, refracted and dispersed.
- Full-Circle Rainbow, which appears to be in circular shape starting from the ground. So when the observer observes this from the ground. The only upper circle can be seen rather the full circle. If suppose, the observer observes from the high point building, the remaining half circle can be figured out.
- Supernumerary Rainbow, in which some few colors could be seen bordering the violet color of the rainbow. Such extra fainted bands are termed as supernumerary bands or supernumerary Rainbows
- Reflected Rainbow and Reflection rainbow appearance happens when the rainbow arcs appearing above the water. A reflected Rainbow appears below the horizon ,whereas the Reflection Rainbow appears above the Horizon.
- Monochrome Rainbow could be seen when a rainbow appears during the sunset or sunrise time due to shorter wavelength
- Higher-order rainbows can be formed due to number of reflections of light into the water droplets. It is possible to produce high order rainbows by lasers. Even the 200th order rainbow was reported to be formed artificially with the help of high bright lights in the laboratory
- Rainbows under moonlight can also be caused and is referred, as Lunar Rainbow .They are very rare and dimmer comparable to that of solar rainbows .Though in presence of spectrum, the color cannot be observed by human eyes.
