Spider web : A real experience with 'Rainbow Effect of Spider web.
[Re-posted on the occasion of belated 'WORLD PHOTOGRAPHY DAY' on 19th August, 2014].
I never thought it would be so amazing and awe inspiring to macrophotograph the rainbow effects of spiderweb. I used my Tamron SP AF 90mm F/2.8 Di macro 1:1 lens, hand held, and it was my lifetime experience with the wondrous macro world. In a dark corner of my garden a cluster of spiderweb got illuminated by a beam of sunlight. And I couldn’t overlook the vibrant colors it created against dark background. As I kept my eyes behind the lens, I saw the web strings, merely few microns in thickness, were vibrating at all possible planes even by mild breeze. I took a series of snaps and it was how they came out……!!
I dedicate this photograph, to all my inspiring flickr friends, and well wishers…with a little poem of mine!!!
When you gave me your inspiration,
I ran miles ahead of time !
When you gave me your torch,
I never saw the darkness behind !
And when you gave me your colors,
I dared to walk on the rainbows !
And I walked on the rainbows !!!
SPIDER WEB FACT:
When natural light passes through almost transparent spider silk, it breaks into constituent wavelengths of visible colors( VIBGYOR ), thus showing a prism effect.
A spider web or cobweb is a device created by a spider out of proteinaceous spider silk extruded from its spinnerets.
"cobweb" is used to describe the tangled three-dimensional web of some spiders of the Therididae family. Whilst this large family is also known as the tangle-web spiders, cobweb spiders or weavers and comb-footed spiders they actually have a huge range of web architectures.
When spiders moved from the water to the land in the Early Devonian period, they started making silk to protect their bodies and their eggs. Spiders gradually started using silk for hunting purposes.
Spiders produce silk from their spinneret glands located at the tip of their abdomen. Each gland produces a thread for a special purpose – for example a trailed safety line, sticky silk for trapping prey or fine silk for wrapping it. Spiders use different gland types to produce different silks, and some spiders are capable of producing up to 8 different silks during their lifetime.
OPTICS
Recently, researchers have used spider web fibers (silk threads) to induce minute disturbances into propagating N-slit interferometric signals, used in optical communications. These optical disturbances are detected in the form of diffraction patterns (Duarte, F.J.; Taylor, T.S.; Black, A.M.; Davenport, W.E.; Varmette, P.G. (2011). "N-slit interferometer for secure free-space optical communications: 527 m intra interferometric path length". J. Opt. 13: 035710. doi:10.1088/2040-8978/13/3/035710.)
