I was jut taking the picture of the morning sun with my canon PS 06 april 2011, morning about 6 am, look for coordinates of Dhenkanal (low res =8 megapixel, user friendly=just click). I clicked the following pictures. I am posting here 3 of them.
And I observed something special I thought about it for a while which I will write in. What we see here is two concentric hexagons one of yellow light (a thin band) and the other an orange band (thicker). I hope you can really see them clearly as it may depend on the nature of your computer screen. There is also possibly a red region after the orange.
This is pretty awesome. The wavelength of yellow is 570 nm and that of orange is 590 nm. This is possibly a great thing since all other light is scattered off. This therefore lies about that scale in a matter of 20 nms. Now most molecules would be of the nm range.
But why such a diffraction occured for these two wavelengths and very interestingly they are hexagons. I searched about Benzene rings a little and see when their Van-der-walls radii and other factors are taken into account it offers 1 nm for “2,4,6-trinitro-toluene (TNT)” and 1.6 nm for ” N-methyl-perrylene-diimide”.
The bond-length of Carbon black and humic acids are of the order 4 nm where as they can form rings upto 40. Also the total molecule width is higher than the bond length (1 order of magnitude!!). That’s still too small to diffract the yellow and orange light or any visible light. SO is there a large new ring molecule or larger molecules in a colloidal form inside or outside of sun that’s present between us and the sun which causes such an effect??
I said colloidal just from a guess but when I did a bit more research (yes wikipedia is filled with many useful info) I see that colloidals of the sizes of 200 nm are mentioned. Also a colloid known as OPAL is known to diffract all visible light components…I might as well have hit upon a new discovery. EUREKA !!
And if we do a little more research we would see that a 200 nm particle can also produce all wavelengths of light from its excitation energy… What’s happening here?? & if you check this research-article you will see a 140 nm particle can have an excitation of yellow (570nm) light: http://www.etseq.urv.es/doctorat/index/web_nanobiotech/handouts/Lecture_16_Handout_12_Nanoparticles.pdf But why the hexagon structure?
and in the evening on the other side of sky…
