During a cloudy day, a primary and a secondary rainbow may be created, then the:
- A primary rainbow is due to double internal reflection and is formed above the secondary one.
- B primary rainbow is due to double internal reflection and is formed below the secondary one.
- C secondary rainbow is due to double internal reflection and is formed above the primary one.
- D secondary rainbow is due to single internal reflection and is formed above the primary one.
