Why do rainbows form? How are they formed?
Fascinating! Is there a way to predict when and where a rainbow will appear?
The conditions required for a rainbow are specific. You need a source of sunlight, a large number of water droplets in the air, and the observer and the sun should be in opposite directions relative to the center of the droplets. This typically happens during or after a rain shower, when the sun is shining and the air is still moist. There's no surefire way to predict when or where a rainbow will appear, but these conditions increase the likelihood of seeing one.
