Montana Rainbow

An intense rainbow arches over southern Montana’s Absaroka Range near Livingston.
I love seeing rainbows - here are a few fun tips about them:
Rainbows are formed when sunlight shines through rainwater. As a result, light reflects off the water droplets, bends (called refraction) and splits.
When sunlight shines through the water droplets, it splits into seven colors. The seven colors of the rainbow are red, orange, yellow, green, blue, indigo and violet. This is called a light spectrum. An easy way to remember the colors in order is to use the name Roy G. Biv.
To see a rainbow, you need to be standing so the sun so the sun is behind you, and the rain is occurring in front of you.
