Find A Rainbow Day

A rainbow is an optical illusion—it does not actually exist in a specific spot in the sky. The appearance of a rainbow depends on where you're standing and where the sun (or other source of light) is shining. The sun or other source of light is usually behind the person seeing the rainbow.

Most rainbows form when the Sun's rays strike raindrops falling from faraway rain clouds. Rainbows appear in the part of the sky opposite the Sun, usually in the early morning or late afternoon. From inside to outside, the colors of a rainbow are violet, indigo, blue, green, yellow, orange, and red.

What is a interesting fact about rainbows? You can never get to the end of a rainbow. Because a rainbow is based on the orientation of the observer (you) and the light source (the sun), when you move, the rainbow will move, too. Find a Rainbow Day is celebrated every year on April 3rd, and there’s no better way to spend a day in early spring.
