Rays escaping after two reflections make a secondary bow. The secondary has a radius of 51º and lies some 9º outside the primary bow. It is broader, 1.8X the width of the primary, and its colours are reversed so that the reds of the two bows always face one another. ... Rainbow Wheel; Dew Bow; Sea Spray Bow;
