Double rainbow and supernumerary rainbows on the inside of the primary arc. Ng book the complete book on angular 4 pdf caused by sunlight always appear in the section of sky directly opposite the sun.

Rainbows can be full circles. In a primary rainbow, the arc shows red on the outer part and violet on the inner side. In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colors reversed, with red on the inner side of the arc. This is caused by the light being reflected twice on the inside of the droplet before leaving it. Thus, a rainbow is not an object and cannot be physically approached.
