   Dew Bow  




Morning dewbow captured by Kevin Boyle. Large dew drops produced the bow by refracting and reflecting light in the same way as do raindrops. The path on the grass of the dew forming the bow is a hyperbola or ellipse formed by the intersection of the rainbow cone with the ground.. However, the bow as seen by your eye, at the tip of cone, is always circular. ©Kevin Boyle, shown with permission.
