Find A Rainbow Day

It can be all three; beauty, hope and promise. (Jill Magnus)
A spectrum of light in the form of a multicolored arc, appearing in the sky, is caused by both reflection and refraction of light in water droplets in the Earth’s atmosphere. These rainbows always appear directly opposite of the sun. The light is refracted (bent) when it enters a droplet of water, then is reflected inside on the back of the droplet and refracted again when leaving it.
Red is the color that is visible on the outer part of arainbow and violet on the inside of a primary rainbow. Children learn in science class the mnemonic ROYGBIV to help them to remember the sequence of colors in a rainbow: red, orange, yellow, green, blue, indigo, violet. Many forms of airborne water can causerainbows including, rain, mist, spray, and dew.

Rainbow FAQ
Q. When is the best time to look for a rainbow?
A. Rainbows often appear after it rains and the clouds have cleared.
The sun casts its rays through the remaining moisture in the air. The
water in the air bends the light into its colors. You can also find a
rainbow near the ground where dew had formed or water from a sprinkler.
Use a prism to cast a rainbow on a wall.
Q. How can I see an entire rainbow?
A. You need to get up into the sky to see the full circle of a rainbow.
If you're on an airplane when it's raining, you might get to see the
entire circle.
Q. Does saltwater refract light differently than freshwater?
A. Yes. Saltwater is denser than freshwater so it will form rainbows with a smaller radius.
