What is National Find A Rainbow Day?
National Find a Rainbow Day is an annual event that takes place in the United States. On April 3rd, we are encouraged to look up the sky and find a vibrant ray of hope cast across it.
Both reflection and refraction of light in water droplets in the Earth's atmosphere produce a spectrum of light in the form of a multicolored arc, which appears in the sky. These rainbows are always visible opposite of the sun's. As it approaches a droplet of water, it is refracted (bent) and then is seen inside on the back of the droplet and then refracted again when leaving it.
On the outside of a primary rainbow, Red is the color that is visible on the outer part of a rainbow and violet on the outside of a primary rainbow. Children enroll in science class with the mnemonic ROYGBIV to help them remember the sequence of colors in a rainbow: red, orange, yellow, green, blue, indigo, violet. Many forms of airborne water can result in rainbows, including rain, mist, spray, and dew.
