I was a little slow off the ground for this post.  This is the last day for submitting to the Weekly Photo Challenge: Refraction.  I was going through photos today to get a few printed for some frames that desperately need photos and I came across this one that struck me as fitting this week’s theme.  My focus is light refraction.

“Refraction occurs, as in a lens, when a wave passes from one medium into the second, deviating from the straight path it otherwise would have taken. The amount of deviation or “bending” depends on the indexes of refraction of each medium, determined by the relative speed of the wave in the two media.”  — Dictionary.com

In other words, when light enters a denser, transparent material it slows down and refraction or bending of light occurs.  Thinks of a pencil in a glass of water.  When you look at the pencil above the water line and compare it to the pencil below the water line, the pencil itself appears fractured.  It is a cool phenomenon.  Rainbows are an example of water droplets behaving like a prism.  The higher density of the water droplets causes the light to separate into its different wavelengths.  Each wavelength is a different color seen as the rainbow!

“Man, Sub-creator, the refracted light
through whom is splintered from a single White
to many hues, and endlessly combined
in living shapes that move from mind to mind.”— J.J.R. Tolkien

This photo was taken with my Canon Rebel digital camera in late August of this year during an evening bus tour.  It was a very muggy evening.  Day time temperatures were very high and that evening was very warm.  With abundant water in the air, the refraction of light through tiny water droplets caused an interesting halo effect around a street light in Little Italy, New York City.
