= impact parameter
= angle for the
-order rainbow
refraction indices for water:
Snapshot 1: the primary rainbow
Snapshot 2: the secondary rainbow
Snapshot 3: violet ray with three reflections
Snapshot 4: secondary rainbow for glass sphere
Snapshot 5: rays after two reflections in a water drop; no rainbow because intensity
