February 11, 2013 – Day 570
The picture below is my response to the Photo Friday challenge of “natural light“.
In February of this year, the family made a trek out to Iguazu Falls (as mentioned before here and here), a stunning natural wonder of falling water that straddles the border of Brazil and Argentina.
As this week’s challenge is all about natural light, please allow me to show you what happens when sunlight interacts with droplets of water.
Why are there so many songs about these arcs?
As you can see from some previous postings (like here and here), I’m a sucker for arcs of color.
