Diagram showing how primary and secondary rainbows are formed due to the light propagation in spherical droplets.
- Spherical droplet
- Places where internal reflection of the light occurs

- Path of light contributing to secondary rainbow
- Observer
- Region forming the primary rainbow
- Region forming the secondary raimbow
- Zone in the atmosphere holding countless tiny spherical droplets
