10 fun facts about rainbows

Answer 1

1. Rainbows are optical and meteorological phenomena that occur when sunlight is refracted, reflected, and dispersed through water droplets in the atmosphere, creating a spectrum of light.
2. The classic rainbow has seven colors: red, orange, yellow, green, blue, indigo, and violet, which can be remembered using the acronym ROYGBIV.
3. Double rainbows occur when light is reflected twice inside water droplets, with the secondary rainbow appearing fainter and inverted in color order.
4. Rainbows are actually circular, but the ground usually obscures the bottom half; from an airplane, you can sometimes see a full circular arc.
