A rainbow occurs when rain is falling in one portion of the sky and the sun is shining in another. For a rainbow to be seen, the sun must be behind an observer who is ... Sunlight is refracted as it enters a raindrop, ... The critical angle for water (which would apply to raindrops) is 48 degrees (relative to the normal).

Extra bands, usually pale pink or green in color, are often seen on the inside of the primary rainbow. They result from interference of light rays which emerge from water droplets in the same direction. ... The number of visible supernumerary arcs depends upon the size of the raindrops.

Commentary on Peace and Justice. ... Rainbows need both the sunshine and rain to appear, so I took it as a sign from God. Tears welled in my eyes as Stevie sang on, "no hungry children, no empty hands". Hope you know the song, because this is a brief look at rainbows, arcs and snowflakes, not Christmas songs.
